Failure In An Air Compressor Engineering Essay

Failure In An Air Compressor Engineering Essay Abstract In this project, the mission which needs to be accomplished is to investigate the relentless root cause of such failure and to give useful recommendations which can help to avoid such failures in the reciprocating compressor under study in the future. An engine driven auxiliary air compressor failed, the air compressor is located in the Hawke workshop. The first stage will be to establish details about the compressor, the manufacturer and how the compressor works. Classification of compressors and types will be also discussed and of course the theory of operation. Collecting components failed in order to be examined subsequently for the failure cause or causes this will be held using a variety of methods. NDE (non-distractive examination) or NDT (non-destructive testing) is valuable way to use for preliminary inspection of the failed parts without damaging it. Discussion of the probable causes for the failure well be performed in the following chapters as well as the conclusion obtained from study conducted. Introduction This project will investigate and analysis a failure happened in an air compressor. This investigation will be done in several ways to figure out the cause of the failure. Air compressor is a machine has the ability to compress the air and release it to convert the electrical power to kinetic energy to use it in several industrials and usages. Air compressor is consisting of many components. These components are electrical motor, pistons, air pump, air receiver, air drier, filters, air pressure regulator and pressure switch. All of these components will be discussed in details in the next chapters. There are also types of air compressor will be discussed later. Background The case which had here is a failure in an air compressor. From the first sight on the damage happened in it, it seems to be that the failure happened in the connecting rod and its obvious from the below figure number 1. This figure shows that the failure happened in the connecting rod from the ring part which connected to a crank shaft. But the reason for this failure is unknown as there are several scenarios could be adopted. The first scenario is the fatigue is the reason for this failure. The second scenario is a very heavy pressure loaded to the compressor which led to that failure. These are the most expected scenarios which will be investigated later in this project to figure out the reason of the failure.

This will be achieved by carrying out the below objectives, once its achieved, the main aim of the project will be achieved. Project objectives: Collecting valuable information about, model number is LP 4, this will include: design of compressor, design of each part, construction materials of each part, operation principles, working theory, production range..etc. collecting data will help to recognize main failure cause, and accordingly to prepare new procedure to eliminate the problem, to decrease the opportunity of failure occurrence in the future, use greater safety factor and to recognize the person or the entity responsible for failure and to make mistake proofing for future avoidance of the failure. Collecting this background information is not limited to numbers only but it is should be extended to everything such as pictures, charts and graphs and samples. Investigating operational parameters, history of operation, nature of operation..etc in order to be able to determine precisely the root cause of such failure and which failure mode it follows. Physical investigation or macroscopic inspection should be carried out. This mission includes photo capturing, code of the product, model number, lot number, batch number and serial number. Perform compressor disassembly in order to dismantle each component, part, assemblies and sub-assemblies to perform through investigation and inspection of each. Its should be mentioned that necessary tests and analyses should be performed; mainly the manufacturer usually has his own procedures and tests for test and inspection. Air Compressor What is the air compressor? Air compressor is a machine that converts electric power to kinetic energy (motion). This energy comes from pressurizing and compressing air. After that, the compressed air goes into a chamber, and the air kept in the chamber by unidirectional valve. There are many types of compressors these types are: reciprocating compressor, rotary screw compressor and centrifugal compressor. These types will be explained in details below. Reciprocating compressor: Reciprocating air compressor is positive displacement compressor. This compressor sucks a volume of air and presses it with high pressure. This pressure done by using a piston and cylinder as movement part and displacement part. The compressor could be single acting or double acting according to its accomplish by using one side or both side. When the pressure difference between the cylinder and the receiver became proper, the valves open. Inlet valves open when the pressure in the cylinder is slightly below the intake pressure. Discharge valves open when the pressure in the cylinder is slightly above the discharge pressure. The compressor could be a single stage when the compression process done parallel. Rotary screw compressor: Also Rotary air compressor is a positive displacement compressor. Single stage helical or spiral lobe oil flooded screw is the most common in rotary air compressor. This compressor is consisting of 2 rotors located in a case where the air is compressed internally without any valves. The cooling for these compressors done by oil. As the cooling for the working parts happened inside the compressor, this type of compressor will not experience over heat due to operation, so it could operate without stop. Due to the simple design of the rotary screw compressor and its parts it can be maintained easily and installed any where could handle its static weight. The 2 stages rotary air compressor uses 2 rotors with a combined air end. This 2 rotors installed in series to share the compression. This raise up the efficiency with 50%. This 2 stage rotary compressor combined the maximum profit from the rotary screw with its simplicity and flexibility and the reciprocating compressor with its effect ive energy when it works 2 stages with double acting. The 2 stages of this compressor could be cooled by water, air or oil. The cooling system for this compressor could be oil, air and water. Centrifugal compressor: The centrifugal air compressor is a dynamic compressor that depends on transfer of energy from a rotating impeller to the air. This done by changing the airs momentum and pressure. By slowing the air in stationary diffuser the momentum converted to pressure. This compressor is oil free compressor. There is a separation between the lubricated oil and air by shaft seals and atmospheric vents. Where the high volume of dry air is required a centrifugal compressor is the proper compressor as it has a few moving parts and could operate continuously. The reciprocating air compressor (knorr-bremse, model lp 4865) The main study object in this project as said before is to study the reciprocating air compressor (knorr-bremse lp 4865). By searching the internet and try to get information about the air compressor which needed to complete this study but unfortunately the required information couldnt be found. So the general information about the reciprocating air compressor will be mentioned instead of the specific air compressor. There are 9 main parts for the reciprocating air compressor these parts are: Crank case: Crank case is a close rigid body where the crank shaft and the bearing house where located. This body could by rectangular or square shape. Mainly crank case formed by using cast iron. Crank Shaft: Crank shaft in one of the most important parts in air compressor. It is a motion transferor. It designed as one piece has balance in its dynamics and tries to avoid any twisting. To ensure a long life for bearings, the polishing and crank pin will be done. Generally crank shafts have a fly wheel. This crank shaft manufactured mainly of high grade S.G iron. Connecting rod: This part is responsible of transfer the motion from the crank shaft to the piston and changing the direction from the rotating motion come from the crank shaft into reciprocating motion in piston. This part is mainly forged of alloy steel. Bearings: Bearings are made to provide the rotating gear with rigidity. Its mainly manufactured of copper lead alloy. Cross slide: to get a perfect running for cross head, this part is responsible for reduce the inertia. This part is commonly manufactured of high grade S.G. iron. Cylinder: This part is where the air flow passes and compressed. Cylinders are manufactured with water jacket to reduce the generated heat from the compression process. This cylinder mainly made of cast iron. Pistons: Piston is the main part in the compression process, which move forward to compress the air and backward to intake a new air amount to compress. There are 2 types of piston according to its lubrication system, the first type is non-lubricated which made from aluminium alloy, and the second type which is lubricated is made from cast iron. Due to moving of piston in the cylinder, so there must a space exist between them, to ensure there is no leak happened for air a piston rings located on piston. Piston rod: Piston rod is this rod which connects the piston to the connecting rod. The piston rod is manufactured of alloy steel. Intake and discharge valves: These valves are responsible for the amount of air sucked or discharged. When the piston in the retraction position the suction valve open to allow the air to get in. when the piston move forward and reach the maximum pressure the discharge valve open. These 2 valves are adjusted to be opened and closed according to the pressure difference between inside the cylinder and the outside. These valves are made from stainless steel even a plate type or spring type. Problem Analysis The first problem in this study is that damage which happened in the connecting rod from ring which connected with crack shaft. As said in the background, there are 2 scenarios leads to this damage. The first scenario is a fatigue accrues in the connecting rod with lead to this damage as it couldnt stand the motion and the pressure any more. The second scenario is an excessive pressure more than the maximum pressure which could be hold by the compressor. At the same time a malfunction in the discharge happened, and this could be taken in consider as it must opened at slightly below the maximum pressure. In both scenarios, the damage in the connecting rod lead to another greater damage in the piston and the cylinder, as the piston start to move in non-liner motion and hitting the cylinder wall. This leads to a serious damage in the compressors piston and cylinder. The second problem is gathering the information about the air compressor Knorr-Bremse Lp 4865. This problem happened as the manufactured company keep the information about this compressor not listed and its material and properties to figure out the reason of the damage, maybe by knowing its maximum pressure or material type to check the fatigue on it. Problem Solution To overcome the second problem a deeply internet search is made with trying to contact with the manufactured company through their website www.knorr-bremse.com, but with no result. So another technique implemented, which is gathering common information about reciprocating air compressor and its common parts and materials. This could be useful but not accoutre.

Uma Sekaran’s Chapter 2 Review

The chapter 2 of Research Methods of Business by Uma Sekaran speaks of scientific investigation detailing on the eight hallmarks of science and the limitations of scientific research in management along with the hypothetico-deductive method of research. The hallmarks or main distinguishing characteristics of scientific research can be the following 1. Purposiveness: The research should have a purposive focus i. e. some definite purpose will be served after the research 2. Rigor: Rigor means carefulness, scrupulousness and the degree of exactitude in research investigations good theoretical base and a sound methodological design will add rigor to a purposive study. 3. Testability: if a certain hypothesis gets developed through unstructured interview or library search, then the hypothesis can be tested by applying certain statistical tests to the data collected for the purpose.. 4. Replicability: The results of the test of hypotheses should be supported again and again when same type of research is repeated in other similar circumstances. The researchers will gain confidence in the scientific nature of the research. 5. Precision and confidence: Precision refers to closeness of the findings to â€Å"reality† based on a sample. It reflects the degree of accuracy or exactitude of the results on the basis of the sample to what it really exists in the universe. Confidence refers to the probability that the estimations are correct. 6. Objectivity: The conclusions drawn through the interpretation of the results of data analysis should be objective i. e. they should be based on facts of the findings of the actual data. The more objective the interpretation of data , the more scientific the research investigation becomes. 7. Generalizability: This refers to the scope of applicability of the research findings in one organizational setting to other settings. The wider the range of applicability of the solutions generated by research, the ore useful the research is to the users. 8. Parsimony: Simplicity in explaining the phenomenon or the problem that occur and in generating solutions for the problems is always preferred to complex research frameworks. In the management and behavioral areas , it is not possible to conduct investigations that are 100% scientific because of measurement and collection of data in the subjective areas like feelings, emotions, attitudes and perceptions. These problems occur whenever one tries to quantify human behavior. Thus , the eight hallmarks of science cannot be achieved in full . The deduction and induction processes are explained as follows Deduction: it is the process of arriving at a reasoned conclusion by logical generalization of a known fact. Induction is the process where a certain phenomenon is observed and then a conclusion is arrived at. The seven step processes in hypothetico-deductive method are 1. Observation: It is the very first stage in which one senses that certain changes are occurring or some new behaviors , attitudes and feelings are surfacing. When the observed phenomenon are seen to have potentially important consequences , then one will proceed to preliminary information gathering. 2. Preliminary information gathering: Preliminary information gathering involves seeking of information in depth of what is observed. Through interviews and library search , the mass of information can be gathered. . Theory formulation: It is a step which attempts to integrate all information in a logical manner so that the factors responsible for the problem can be conceptualized and tested. The theoretical framework formulated is often guided by experience and intuition. Here the critical variables are examined as to their contribution or influence in explaining why the problem occurs and how it can be solved. 4. Hypothesizi ng: From the theorized network of associations among the variables, certain testable hypotheses or educated conjectures can be generated. The hypothesis thus generated is tested to determine of the statement is supported. 5. Further scientific data collection- After the development of the hypothesis, data with respect to each variable in the hypothesis need to be obtained. 6. Data analysis- The data gathered are statistically analyzed to see if the hypotheses that were generated have been supported. 7. Deduction – It is a process of arriving at conclusions by interpreting the meaning of the results of the data analysis.

Most Influential Books on Leadership Essay

Leadership is an issue which has been in the limelight in every aspect of human governance. Human development has been linked with management and directions which are part of leadership. Various characteristics of leadership have therefore been identified from various areas in life. This paper aims at identifying three different types of books on leadership which are recognized to be the most influential. The first choice is the book â€Å"Talent Is Never Enough: Discover the Choices That Will Take You beyond Your Talent† by John C. Maxwell . The author holds that talent is never enough in leadership. There are many different people in the whole world , thus showing that talent will never end. Nevertheless if acquiring that talent were just enough for everybody, then we would all be at a higher level and being full of potentials. There are therefore other things that need to be included in our talents so as to be able to discover those opportunities especially when it comes to business. People need to come up with other discoveries which would take them more steps beyond the talents they have. In businesses today, most leaders mostly concentrate more on the talents they have alone. The writer of this book, who in this case is a known expert in leadership – John C. Maxwell – argues that this is not the right way to achieving success. In his discourse, he describes how highly talented people who are globally known would be very successful if talent was the only contingency for that matter . That is not however the case. The book goes on to place more emphasis and support the writer’s decision by highlighting the fact that society is full of people who could have been great men and women if only they used other ideas apart from what they call talent. The author talks of prominent people like Jefferson, Nameth, Churchill, Bono, Oprah, and Dickens whom, apart from their talents, went steps ahead to the next level of increasing their talents and maximizing it to improve the world. They employed more efforts to what they discovered as their talent to capture other opportunities in life. That is why they are the talk of the world. According to Max, talent should therefore be present. It should however be followed by other measures that improve it. With different examples given of those people who maximized their talents, there are a few who did not. The author thus goes ahead to encourage the reader to support the author’s views and improve their lives by giving thirteen key choices one can adopt to become a person with advanced and maximized talent (Maxwell J. C(2009). The second selection of the most influential leadership books that I would recommend is â€Å"The Skinny of the Art of Persuasion† by Jim Randel. In leadership, persuasion is one of the most important skills that a leader should posses. This book provides sound and detailed information on persuasion in leadership. Moreover, it offers other important recommendations on persuasion from various prominent leaders. The book advices on persuasion thanks to the fact that the author is an attorney besides being well experienced in the field. Further, apart from his experience Randel quotes people like Kevin Hogan, James Speakman, Dave Lakhani, Dale Carnegie, Robert Cialdini, Tom Hopkins, Malcolm Gladwell, and others in his discussion on persuasion in leadership. This approach puts more emphasis on the author’s concept. He states that persuasion basically involves integrity. To add to his topic, Randell gives his personal life stories regarding leadership which still bothers him till then. To understand and get acquainted with what he is insinuating, his book finalizes with tips which are easy to understand about a good persuader in leadership (Alegre M. 2010). The third influential book on leadership is John Ferling’s new book on â€Å"The Ascent of George Washington. † It talks about the relationship between leadership and education. It is very important -especially in the current world – to link leadership with the educational backgrounds of those aspiring to be leaders in future. George Washington was an educated man in leadership. He had focus in his politics due to the great boost from his education. This is an ideal model of how leaders should learn to lead others. The author in this book goes ahead to reveal Washington as a political genius due to the fact that he was politically focused, ambitious, and was driven to succeed. Although described by the author as the most untactful and indecisive in times of crises, Washington was the only right person to lead Americans to independence. His character, boldness, judgment, industriousness, determination, and skillful political thinking were remarkable. It is a book that explains how one does not need to be perfect to achieve greatness (Alegre M. 010). Therefore, these books cover some of the most important aspects of leadership which most people fail to identify while leading others. Since most of us are leaders in one way or another, it is equally important to consider reviewing such influential leadership books to acquire various tips of leadership and also – as stated by Maxwell – to improve our talents in leadership. This strategy will not only boost our leadership qualities, but will also enable us to identify new opportunities in life and be able to pursue only the best of them.

Flanery Oconner Good Country People - Free Essay Example

Sample details Pages: 8 Words: 2531 Downloads: 8 Date added: 2017/09/26 Category Literature Essay Type Narrative essay Did you like this example? In A Good Man Is Hard To Find, OConnor introduces the reader to a family representative of the old and new Southern culture. The grandmother represents the old South by the way in which she focuses on her appearnace, manners, and gentile ladylike behavior. OConnor writes her collars and cuffs were organdy trimmed with lace and at her neckline she had pinned a purple spray of cloth violets containing a sachet. In case of an accident, anyone seeing her dead on the highway would know at once that she was a lady(OConnor 118). In this short story, the wild diproportion of the terms, the vapid composure that summons up the ultimate violence only to treat it as a rare social opportuinty, and the cool irony with which OConnor presents the sentence makes it both fearful and ludicrous(Asals 132). The irony that OConnor uses points out the appalling characteristics of the grandmothers self-deception that her clothes make her a lady and turns it into a comic matter. Flannery OConnor g oes to great length to give the reader insight into the characters by describing their clothes and attitudes. The fact that the grandmother took so much time in preparing herself for the trip exemplifies the old Southern tradition of self-presentation and self-pride. The grandmother takes pride in the way she presents herself because she wants everyone to know that she is a lady. Baileys, the grandsons, family represents that of the new Southern culture that is more open to change, but they are not totally receptive to change. OConnor describes the childrens mother in contrast to the grandmother by what they are wearing; thus their clothes represent the age from which they are. The Childrens mother still had on slacks and still had her head tied up in a green kerchief, but the grandmother had on navy blue straw sailor hat with a bunch of white dot in the print(OConnor 118). The childrens mother is representative of the New South in which the Southern Lady is becoming less of a central figure within society. A lady of the old south would never wear slacks and tie her hair up in a kerchief to go out in public. Under an old south mentality these actions would be considered very unlady like. OConnor illustrates the tension between the old and the new south by the constant struggle between the grandmother, her son, and the daughter-in-law. OConnor also poses the contrast between the old and new South in her short story Good Country People. Mrs. Hopewell and Mrs. Freeman represent the old South because of the way in which they carry themselves and their traditional beliefs and values. Mrs. Freeman works for Mrs. Hopewell who states the reason for her keepin her so long was that they were not trash. They were good country people(OConnor 272). Mrs. Hopewell describes Mrs. Freeman and her two daughters as two of the finest girls she knew and Mrs. Freeman was a lady and that she was never ashamed to take her anywhere or introduce her to anybody they might me tt(OConnor 272). In contrast to Mrs. Freeman and Mrs. Hopewell, Joy/Hulga represents the new south that is not concerned with self presentation in the way that the grandmother is in A Good Man Is Hard TO Find. Joy/Hulga did not care to participate in the morning gossip between the older ladies. OConnor describes Joy/Hulgas disregard for the old south and its sense of manners: When Hulga stumped into the Kitchen in the morning (she could walk without making the awful noise but she made itMrs. Hopewell was certainbecause it was ugly-sounding), she glanced at them and did not speak. Mrs. Hopewell would be in her red kimono with her hair tied around her head in rags. (275) OConnor juxtaposes Joy/Hulga to her mother, Mrs. Hopewell, by contrasting her mannerism, clothes, and overall demure. Joy/Hulga is described as making awful noises in contrast to her mother whom is sitting in her red kimono across the kitchen from her. Mrs. Hopewells name is symbolic of her very hopeful and opti mistic nature. Joys changing her name to Hulga represents her renouncing of the old Southern traditions imposed by her mother. Joy/Hulga does not conform to the social codes of the old south because she deliberately makes grotesque and unlady like noise and does not apologize for them. Joy/Hulga is forced by her physical disabilities to live at home, the girls existence has become one continuous of outraged rejection of the life around her(Asals, 103). Joy/Hulga is also set apart from the old south because she has obtained a PH. D. in philosophy. OConnor writes Mrs. Hopewell thought it was nice for girls to go to school to have a good time but Joy had gone through. The girl had taken the Ph. D. in philosophy and this left Mrs. Hopewell at a complete loss. You could say, My daughter is a nurse, or My daughter is a schoolteacher, or even, My daughter is a chemical engineer. You could not say, My daughter is a philosopher. (276) Mrs. Hopewell feels that it is unlady like to pursue an education that far, but Joy/Hulga disregards this old southern sexist attitude about women and education. Joy/Hulga thinks she has defined a self that is the antithesis of her mothers(Asals 104). Education and mannerisms of the old and new south are not the only contrasting views that Flannery OConnor explores in these two short stories. Christianity and fallen human nature are two other aspects that bring depth and ironic twists to A Good Man Is Hard To Find and Good Country People. In both stories, OConnor explores the ideals and hypocrisies of the Christian religion and faith. Within OConnors writings, the traditional Christian themes of fall and redemption, nature and grace, sin and innocence are explored (Bleikasten 138). In A Good Man Is Hard To Find, OConnor questions the faith and beliefs in Christianity of the grandmother. At the closing of the story, when the grandmother is facing her own death, the Misfit says: Jesus was the only One that ever raised the dead a nd he shouldnt have done it. He thrown everything off balance. If He did what He said, then its nothing for you to do but throw away everything and follow Him, and if He didnt, then its nothing for you to do but enjoy the few minutes you got left the best way you canby killing somebody or burning down his house or doing some other meanness to him. OConnor 132) The Misfits view illustrates the active presence of an Evil force within the society. The grandmother assumed that if you came from good people that you would naturally be a good person. In contrast to this view of the old south, OConnor presents the reader with a world haunted by the sacreda sacred with two faces now distinct and opposed, now enigmatically confused: the divine and the demonic, and in her fables the battleground where these two antagonistic powers confront each other and fight for possession of each mans soul(Bleikasten 139). The grandmother represents the active and faithful Christian servant, and the Misf it is symbolic of the devil or an Anti-Christ figure. Despite all of the good deeds that the grandmother has accomplished, God is not there to help her in her time of need. The old southern and traditional secular view was that good deeds would lead to a good life, but OConnor recognizes that there is also an active force of Evil and presence of the Devil in this world. OConnors antisecular and antiindividualistic views are also present in her short story Good Country People. Within this short story, the reader is presented with two differing views of religion: the devout Christian and the atheist. The devout Christians, Mrs. Hopewell and Mrs. Freeman, represents the old south as does the grandmother in A Good Man Is Hard To Find. OConnor criticizes the old southern Christian for being faithful and trustful in A Good Man Is Hard To Find, yet the reader the does not quite know what to make of the ending in Good Country People. The story ends with the atheist being decieved by one who pretends to be a Christian. OConnor could be presenting the reader with the view that one is not able to really tell the difference between good country people and Christian or liars and cheats. Good Country People can be read as exploiting the idea that one is not able to tell the difference between Christians and non-Christians based on their appearance and actions. The old south puts their trust and hopes into appearances, while the new south is more reluctant and cautious. This is not to say that they cannot be decieved because the reader sees what happens to Joy/Hulga in the end. Joy/Hulga is an atheist who dismisses all Christian beliefs by saying in my economy Im saved and you are damned but I told you I didnt believe in God(OConnor 286). She compares her realization to the Christian salvation by saying we are all damned but some of us have taken off our blindfolds and see that theres nothing to see. Its a kind of salvation(OConnor 288). Joy/Hulga believes that sh e is saved from the hypocrisies of the Christian faith, and she represents the new south because she is open to different interpretations. She feels that she as been saved from Christianity, but OConnor raises the question: is she really saved at all? Joy/Hulga sets off to seduce Pointer, the Bible salesman, and she imagined that she took his remorse in hand and changes it into a deeper understanding of life(OConnor 284). Ironically, it is Pointer that teaches Joy/Hulga the lesson that needs to be learned. He turns on her and steals her wooden leg. In a fit of rage Joy/Hulga bursts out Youre a Christian! Youre a fine Christian! Youre just like them allsay one thing and do another. (OConnor 290). Joy/Hulga is not able to tell the difference between him and Mrs. Hopewell and Mrs. Freeman. She feels that by setting herself apart from Christianity she is saved from its pitfalls and hypocrisies. In reality, she is not saved from it at all. Pointer returns her comment saying I hope y ou dont think that I believe in that crap! I may sell Bibles but I know which end is up and I wasnt born yesterday and I know where I am going! (OConnor 290). OConnor presents the reader with a critique of religion and Christianity in both of her stories. Joy/Hulga beleives that all Christians are the same, but OConnor points out that there are all types. Pointer pretends to be a Christian in order to prey off of their needs and insecurities. Joy/Hulga is taken in by his charming and trustworthy persona, but she is unable to see his false motives. Good Country People points out that people do not always prove to be who they portray. The reader is left doubtful and questions the idea of naturally good people and questions value of the Christian faith. While critizing the Christian faith and practices, OConnor also raises the issue of fallen human nature. The Misfit in A Good Man Is Hard To Find and Pointer in Good Country People both represent a character of fallen human natur e. OConnor explores the idea of fallen human nature. The Misfit comes from a good family, and he states God never made a finer woman than my mother and my daddys heart was pure gold(OConnor 127). OConnor questions how someone from such a good family can turn out to be so evil? Fallen human nature is one explanation posited. The Misfit retorts the grandmothers argument that he is a good man saying, Nome, I aint a good man but I aint the worst in the world neither(OConnor 128). He has the self-realization that he is not a good person. He does not know where it is that he went wrong, but he states, I never was a bad boy that I remember of but somewhere along the line I done something wrong and got sent to the penitentiary. I was buried alive(OConnor 130). The Misfit admits that he was once good, but he is unable to determine the source of his fallen human nature. OConnor presents us with another character in Good Country People of fallen human nature. Pointer does not argue tha t he was once good; instead, he tells Hulga, you aint so smart. I been believing in nothing ever since I was born! (OConnor 291). Pointers character illustrates that one can be born with a fallen human nature, or he is made that way by society from the time he is born. In contrast to the Misfits fallen human nature that comes about when he is older, Pointer began falling the day he was born. The idea of fallen human nature is contrasting to the ideas of the old south. Good country people were assumed to always be good, and the old south also thought bad people were born that way. OConnor posited the idea that the society in which one lives can influence a person to change. The Misfit was raised by nice folks, and the old south would have assumed that he would be nice. The grandmother repeatedly argues that I know you came from nice people! (OConnor 132). Bailey, the grandmothers son, realizes the situation that they are in, and he knows that the Misfit is not a nice person. In Go od Country People, Pointer portrays himself as a good country person, and he states, Im as good as you any day in the week(OConnor 290). Pointer dismisses the old souths view that there are good people in this world, and he argues that he is not a bad person. OConnor explicitly explores the themes of Christian theology through Pointer and the Misfit in A Good Man Is Hard To Find and Good Country People. In addition, she presents the reader with the differing generations of the old and new south, and she illustrates the ontrasting views between the two. OConnor is not afraid to question Christian theology or the Southern culture. Her irony and satire add depth to ther stories, and her deep cultural analysis of the South brings a higher level to her writings. OConnor also explores the concept of fallen human nature and how it is brought about. Overall, OConnors works prove to be very in depth in both her social and cultural analysis of the South. She is not afraid to critique the soci ety in which she grew up and lived. Bibliography Asals, Frederick. Flannery OConnor: The Imagination of Extremity.
