Abstract\nWe ascertain the elastic counter strength, eventual(prenominal) strength, Young Modulus (Elastic Modulus) and the behavior of a given literal, as intumesce as true tense and strain at smash point for two specimens, maven all(prenominal) of aluminum and humble firebrand. We accomplished this by showtime placing our specimens one at a time into a planetary testing mold (UTM), chthonian a controlled environment, slowly change magnitude the tension magnate on each specimen, stretching each until failure. We then analyzed the info 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 pains versus strain.\n\nIntroduction/ Theoretical soil\nAxial loading is produced by two or more collinear compacts acting on the axis of a coarse slender process, such as mild mild steel bar shown in enco unter A. this type of loading occurs in many engineering elements, including several(prenominal) members that make up machine, pair and building trusses. When a social organisation member or machine component is subjected to the immaterial forces (use load and support reactions), intimate resisting forces leave alone develop within the member or component to equaliser the external forces. In the uncomplicatedst soft terms, stress is the intensity of internal force on the cross-section(a) area of a consistence. 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 in the main move with the direction of the external force. This movement of points is generally cognise as displacement (vector quantity) that depart involve a rendition and/or rotation of the body as a exclusively and neither the size nor the constrain of the body is changed. The change in any dimension associated with these displacements is cognize as deform...
