The main function of the solar sail is to generate electrical power from solar radiation. The
main requirements for the solar sail are as follows:
(a) Foldable: It should be foldable so that it can be stored compactly before deploying
(b) Lightweight: It should be light to reduce fuel requirement for the spaceship during
launch from earth.
(c) Does not degrade: It should not corrode or degrade.
(d) Able to harvest energy: It should be able to harvest solar radiation when used in space.
Based on our discussion in Chapter 1, write an essay to select the most suitable material class. In
your essay, justify your selection in as much detail as possible.
Your essay should address/contain the following:
a) State the class or family of material you feel would be suitable.
b) Relate the relevant properties between the material class selected with its structure
(bonding type, etc). Be as technical as possible using concepts that we have learned
in ME 201.
c) Discuss how non-engineering factors that you feel need to be considered; such factors
could be cost, etc

Sample Solution

In a sociological perspective, the wholesomeness of crime can be substantiated in a number of ways. From the functionalist view we follow the words of Emile Durkheim, a French sociologist who clarified the normality and necessity of crime. He believed that crime “is a normal aspect of society and crime itself serves a social function” (Law and Society, 2012). He considers crime to simply be deviant behavior that violates social norms, and it is under the adverse reactions by society toward these behaviors that law is hence created. Crime allows an effective amount of change within society, according to Durkheim it clarifies moral boundaries and affirm positive norms, encourages unity and promotes social change. When people are made aware of the inevitability of crime, it triggers a mass contemplation of whether the violated social norm is valid or not (Thompson, 2009). For instance, homosexual relationships were illegal in the US before 2004, and until that point being a homosexual was considered an immoral act that violates common norms. But the legalization of homosexuality was later made possible when the irrationality of criminalizing gay relationships was publicized. More and more people began to understand the problem of groundless accusations in our predominant social norms and legal systems, and it coherently transformed into motivation for social change. In the conflict theory perspective, crime can be seen as a safety valve. This means that if we allow the public to satisfy themselves with the freedom to exercise a certain amount of deviance, more stability and peace can be achieved (Hamlin, 2009). The legalization of prostitution, for example, can serve the function of a safety valve without threatening the institution of the family. Through collectively recognizing the negative impacts of crime can also pull people closer to each other, and can help us gain a sense of belonging. After the 2017 Manchester bombing incident there was a continuous uproar on the internet with people from all over the world expressing their empathy for the unfortunate victims. The world came together in the form of campaigns, hashtags and charity. With a common enemy, it allows us to achieve a new level of harmony and patriotism. In this case, crime serves as a welcome reminder that our darkest hours are always followed with moments of warmth and unity.
