Practical 1 - Assignment Example Annealing process effects on mechanical properties of the sample’s test strain properties. The material loses its ductility during the cold rolling process. Anneal strengthening effect or toughness of the material under investigation (copper) increases in degree of prior cold work and the corresponding annealing. The ability of crystalline material to plastically deform depends on the ability for dislocation movement within copper. When the movement of dislocations is impeded, the material is strengthened. This is achieved through a number of ways such as; Strain hardening or work-hardening or cold working is a process that makes copper harder and stronger through plastic deformation. As it is plastically deformed, dislocations move as additional dislocations are produced. As dislocation within the material increases, the grains interact and become pinned or tangled. As a result, there is decreased grain mobility of dislocations as the material is strengthened. Ductility increases with the grain size, as the strength decreases. Atomic diffusion occurs as temperature increases and it releases internal strain energy. Since atoms are not fixed in a position but move once they have enough energy to break their bonds, diffusion increases rapidly with the increase in temperature. This allows the atoms to move to unrestrained positions and recover a normal position in lattice structure. This is the recovery phase and leads to adjustment of strain. In the annealing process, the test sample was performed in 1000Â ºC capacity furnace. It was observed that the hardness of the copper sample increased with gradual increase in reduction in cross-sectional area. This is due to strain hardening. The maximum value of hardness was obtained at 117HB 40% reduction in area. Understanding of mechanical deformation properties ensures efficient stress relieving procedures. Thickness of material affects the hardness of the material. It is observed from the experiment that

Relativism and Morality - Essay Example From this research it is clear that violation of another human being and to society with the taking of a life is universally wrong; it cannot be comprehended nor excused except in very few cases where violence begets violence. Warfare and the making of war between factions can be said to be racially motivated, territorial motivated, self-interest motivated, religiously motivated and politically motivated. None of these reasons present a strong enough argument to be the deciding faction which starts a conflict such as war. Responding in like becomes a very difficult position to be in for all of society. Taking quick action such as Goodman suggests would seem to be the best choice to avoid the mass murder of millions in a tense situation but look how we have responded to 9/11, a conflict that is still going on despite the death of the leader the United States initially sought. War unites and disunites people unlike any other act. Terrorist usually have a purpose or message behind their violent acts of destruction though these messages and purpose are immediately discounted when the act becomes violent and takes human lives that should be valued above all other considerations. Terrorism uses media sensation to gain national attention to a group or faction self-interested purpose, policy, religion, or idea. Media must take some responsibility in ascribing so much coverage and attention as to elicit repeats of similar behavior though citizens want to know what is going, regardless of their opinion on the issue. By our very actions we further feed the terrorist’s actions and it is a repetitious cycle....

Human trafficking and slavery are just as deeply wrong, though I would imagine for the one being enslaved there must be periods of time that are so hateful that they are only thankful to be alive and not much else. It is pointed out that drugs, which are extremely scrutinized and resisted by the United States are sold merely once, while human beings can be sold repeatedly. Incest and human trafficking are to a much greater degree fundamentally wrong while polygamy can be situational. I disagree with Goodson’s views in this area, he uses the statement that polygamy diminishes intimacy and trust and transforms the nature of marriage which I believe that once again he is relying on language and communication as relationship factors, and societal standards which as his whole paper describes are obviously seriously out of order and frequently wrong because as a society we are extremely divide. I do not feel it is a morally wrong act to be a polygamist unless it involves minors marrying or situations that preclude to incest or child endangerment. Rape and clitoridectomy distorts
