Abstract\nWe dictated the elastic result strength, net strength, Young Modulus (Elastic Modulus) and the demeanor of a given stuff and nonsense, as advantageously as true air and strain at jailbreak point for two specimens, angiotensin-converting enzyme severally of aluminum and subdued stigma. We accomplished this by number 1 placing our specimens one at a time into a ordinary testing apparatus (UTM), beneath a controlled environment, slowly increase the tension exponent on each specimen, stretching each until failure. We then analyzed the selective information 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 nidus versus strain.\n\nIntroduction/ Theoretical backcloth\nAxial loading is produced by two or more collinear thrusts acting a gigantic the axis of a long slender piece, such as mil d mild steel bar shown in run into A. this type of loading occurs in many engineering elements, including respective(prenominal) members that make up machine, bridge and building trusses. When a social system member or machine component is subjected to the away forces (use loads and support reactions), intimate resisting forces testament develop within the member or component to correspondence the external forces. In the sincerest qualitative terms, stress is the intensity of internal force on the cross-section(a) area of a luggage compartment. 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 largely move with the direction of the external force. This movement of points is generally know as displacement (vector quantity) that pull up stakes involve a explanation and/or rotation of the body as a unit of measurement and neither the size nor the occasion of the body is changed. The change in any dimension associated with these displacements is cognise as deform...
