Problem 19.D1

Railroad tracks made of 1025 steel are to be laid during the time of year when the temperature averages 4C (40F). If a joint space of 5.4 mm (0.210 in.) is allowed between standard rails of length 11.9 m (39 ft), what is the highest possible temperature that can be tolerated without the introduction of thermal stresses?

Step-by-Step Solution:
Step 1 of 3

Here is a good study guide for you to follow for your mid term exam: 1 How would you describe culture Culture refers to the meanings and ways of life that characterize a society. So I would describe culture as the characteristics and knowledge of a particular group of people, such as language, food, social practices, and music 2 How would you describe social problems Since there is no universal, constant, or absolute definition of a social problem. I would describe a social problem as a problem that effects everyone, whether it’d be directly or indirectly. It can be a wide array and very diverse group of issues because a lot of things fall into that category, from politics to race to internet safety issues. 3 What would society be like without a social structure There would be social chaos. There would be no socioeconomic stratification; Social Structure is organized into four different parts­ institutions, social groups, statuses, and roles. 4 Could you defend a Marxist point of view on sociological problems It can be defended; Marxist explanations of social problems imply that the solution lies in eliminating inequality among classes of people by creating a classless society. So no one would be better than the next person based on a societal point of view. I am not sure I can completely defend it because I believe that people will class themselves just based on America’s history since we were all separated by economic standards at one point; much like segregation. 5 Do you find yourself agreeing or disagreeing with Blumers model of social problems I find myself agreeing with Blumer’s model of a social problem because it simplifies it. He breaks it down so the average person can recognize it as a social problem. He does this through stages, beginning with social recognition, next social legitimation, then mobilization of action, and finally development and implementation of an official plan. 6 Which method of research would you recommend to study a social problem, survey, interviews, experiments Experiments; surveys are too vague, social problems require explanations and observation, which is why and interview won’t do either. With interviews, due to human nature, they are going to want to come off as positive as possible as opposed to realistic. Conducting an experiment where you can observe them in their natural habitat is the best way to attain a real sense of research. I like how you can observe how one variable affects another in a casual relationship. 7 Do you believe residents of the US engage in healthy behavior I believe U.S. residents engage in healthy behavior to an extent. Economically as far as pursuing a career, majority of Americans can do stand are very driven. On the other hand, engaging in drugs and alcohol is not healthy. You can also talk about the increasing obesity rates which is unhealthy; also spousal abuse. It depends what the discussion is because there are so many ends of the spectrum you can go off as far as healthy behavior. 8 Why do so many young adults students suffer from a mental illness I think it is from the stress of college and entering the working world. Mental health problems are not uncommon for a college student. 1 in 4 college students suffer from a mental illness. Most mental illnesses they suffer from are anxiety, depression, bipolar disorders, and panic attacks. 9 What did you learn from you paper on Obama health care I initially didn't know much about it, however after conducting a good amount of research I learned that it is too complicated. It is not easy to understand for the Average American making it easy to mistake its advantages and disadvantages. It’s in need of simplification. 10 Is the US health care system broken and in need of significant or minor change US Health care system is broken. Healthcare is something that everyone should have easy access to for it provides prevention of diseases and epidemics in addition to education towards certain diseases that could potentially prevent something from happening and encourage a healthier lifestyle. Its broken in a sense that our economy won't allow it, and money is needed in order to provide research so that different cures can be continued to be found. Healthcare is a social institution that functions to maintain the well­being of societal members and, consequently, of the social system as a whole. This definition itself shows obvious flaws in healthcare. 11 What are your thought about legal drug abuse and illegal drug usage in the United States Legal Drug use, if used responsibly is fine. However, like every drug, legal or illegal, it has potential to be abused. For example alcohol­ the drug of choice can easily be abused with heavy or binge drinking. Illegal drug use, is a problem. They are illegal for a reason. They're highly unhealthy for your body and can attack your major organs. however it is still being used by U.S. residents 12 Are the US drug laws too harsh. Why or why not In my opinion yes. Drug law sentences should not be almost equal to murder crimes or armed robbery. Carrying an ounce of marijuana should be punishable by law, but shouldn't exceed a year. No one was hurt, killed, and property wasn't stolen. Obviously there is a war on drugs so I believe federal law officials are trying to instill fear in anyone involved with drugs, thats why the penalty is so high. 13 What does crime mean to you Crime is something that violates the federal, state, or local law. Usually it affects another person negatively whether its physically or mentally; however a lot of federal and white collar crimes does not have a victim or include another person. For example prostitution or drug possession. 14 Have you ever been the victim of a crime If so what type and kind No. 15 Can you measure crime in dollars If so how Yes. Crime is expensive. it can cost a lot of money to a victim who has had something stolen. But as far as prosecuting someone it is very expensive; and the cost raises based on the severity of the crime. It is also expensive to control crime, transfer property, and treat crime victims who may have gotten hurt in the process. There is a big price of crime. 16 What did you learn about your paper on TV and culture I learned that in American Culture a pattern was developed. Television, a big pop culture outlet, has influenced American culture as far as family relationships, spousal relationships, attitudes towards certain topics, and the way we interact with one another. 17 How have American families changed in the last 50, 25, 10 years American families have changed a number of ways in the last 50, 25, and 10 years. I think Division of Power in the Family is one of the biggest changes. More and more women are becoming the breadwinners of the family an taking care of bills. There is also an increase in single­hood and older age ant first marriage. 18 What exactly is an abusive relationship When someone is implicating physical or emotional violence towards their spouse with the intention to hurt them. Some examples are common couple violence, intimate terrorism, violent resistance, and mutual violent control. 19 Is family violence overplayed in our court systems No. Violence is violence, so I believe that it is an issue that needs to be brought into the light in order to come to a solution. Whether that’d be an abuse program or foster homing for the child. 20 How would you describe the social service system in the US I would describe it as helpful but flawed. It helps to prevent homelessness along with increasing the chances of an individual attaining an education and bettering his/her life for the future; however it is capable of being take advantage of. 21 What are some problems that confront our Public Assistance programs That it can be taken advantage of, it keeps people in a financial hole, the housing provided is mediocre, and most reside in the “slums” of their areas. 22 Is there really such a thing as underemployment Yes. The needs of these people are never met along with he fact that they are undercounted.The underemployment rates are higher that unemployment rates. 23 What are your thoughts on labor unions Are they something of the past I am not a big advocate of it because it can easily be used to abuse a person. Most people working in labor union does not know their rights and what they should be provided by a employer. I think it should be a thing of the past. 24 What does McDonaldization really mean McDonaldization to me means that life is starting to become similar to a fast food restaurant in terms of efficiency, calcuability, predictability, and control through technology.
