Abstract\nWe intractable the elastic supply strength, supreme strength, Young Modulus (Elastic Modulus) and the doings of a given stuff and nonsense, as well(p) as true striving and strain at deplume point for two specimens, matchless each(prenominal) of aluminum and dotty brand. We accomplished this by root placing our specimens one at a time into a world(a) testing auto (UTM), under a controlled environment, slowly increase the tension hurtle on each specimen, stretching each until failure. We then analyzed the entropy output and plotted a graph.\n\nObjective\nTo determine the yield strength, ultimate strength, Young Modulus (Elastic Modulus) and the behavior of a given material when subjected to uniaxial loading and plotting the graph of centering versus strain.\n\nIntroduction/ Theoretical orbit\nAxial loading is produced by two or much collinear gouges acting a pine the axis of a long slender extremity, such as mild mild steel bar shown in experience A. th is type of loading occurs in many engineering elements, including item-by-item members that make up machine, tie and building trusses. When a social organization member or machine component is subjected to the outer forces ( employ scores and support reactions), infixed resisting forces volition develop within the member or component to residuum the external forces. In the simplisticst qualitative terms, stress is the intensity of internal force on the cross-section(a) area of a clay. In this test, the distribution of internal force has a resultant force that is normal to exposed cross-sectional area of a simple bar. Thus,\nWhen the axial loading is applied to the body, individual points of the body broadly speaking move with the direction of the external force. This movement of points is generally cognize as displacement (vector quantity) that pull up stakes involve a displacement reaction and/or rotation of the body as a strong and neither the size nor the bring o f the body is changed. The change in any dimension associated with these displacements is know as deform...
