Materials Engineering - Assignment Example The bondage between the molecules is broken. In this region, the material can regain its original shape after the removal of the loading or rather the stress. At this juncture, the material obeys Hooke’s law and the stress and strain relate proportionally, and the constant of proportionality is the modulus of elasticity. The structure of the particles is not altered which explains the reason the material regains it original shape after the removal of the stress. It is the region just after the elastic limit. It is characterized by the graph flattening indicating destroyed proportionality between the stress and strain. Plastic deformations creep in, and the material loses the ability to regain fully its shape and size after the stress has been released. It takes place due to rearrangement of the molecular or atomic structure that allows for the new shape and size. Found just after the yielding region. It is characterized by a slight rise of the curve to the ultimate stress point. The behavior is due to the strength of the deformed atoms or molecules having a slight ability to withstand more stress up to the point beyond which complete deformation takes place. The rise of the curve in this region is what is termed as strain hardening. It is the region beyond the ultimate stress point. In this region, a further increase of the stress leads to a reduction of the cross section of the material only in some parts and not the entire material. The constrictions formed are what is referred to as necking. It is the continuous reduction of the cross section area that leads to the breakage and thus separation of the material. Metallic materials are ductile thus has the ability to deform plastically up to some extent. On the graph, it is represented by the region beyond the proportional limit where the elastic limit has been exceeded. Force

Letter of Motivation in masters of public policy Essay

Letter of Motivation in masters of public policy - Essay Example As a responsible citizen I would like to participate in the process of addressing delicate questions of internet regulations, regarding protection of privacy, security and access of information. The main problem is the misuse of these media for crimes including terrorist activities. Thus, I personally feel that framing suitable public policies has become a matter of top priority in the modern world. My basic interest in this branch of academics stems from my realization of the problem in its right perspective. I further feel that I will be able to contribute to positive outcomes in this regard, if I can combine personal interest with academic knowledge. My keen interest in gaining in depth knowledge on this topic and my yearning to contribute to this field has bred in me the desire to pursue a Masters in Public Policy. I want to explore the possibilities ICT holds for improving information and service delivery. In order to achieve my objectives, a more pluralistic approach for internet governance is required. This will enable me to incorporate in my professional life an understanding of the different industries affecting public policy today. The MPP program, in its broad and contextually imbedded approach, would provide ample opportunities to develop and expand the necessary skill sets to understand technology driven governance. I am eager to develop an understanding of the complexity behind the questions of media globalization and to master the skills to analyse and employ this shift of power in modern democracies. I also expect the course to equip me with the ability to understand these two forces which are indispensable in the c reation of modern public policy. My degree in Global Communications and Business Administration from the American University of Paris, serves as a solid base. I chose this program to establish a broad perspective of cultural,
