Abstract\nWe determined the flexile yield strength, net strength, girlish Modulus (Elastic Modulus) and the behavior of a give material, as well as true tenor and strain at rupture sign for devil specimens, wholeness separately of aluminum and buggy steel. We execute this by first placing our specimens one at a fourth dimension into a universal examen machine (UTM), under a controlled environment, slowly increased the accent strong point on severally specimen, stretching each until failure. We whence analyzed the data outfit and plotted a graph.\n\n nonsubjective\nTo determine the yield strength, ultimate strength, Young Modulus (Elastic Modulus) and the behavior of a given material when subjected to uniaxile core and plotting the graph of stress versus strain.\n\n submission/ Theoretical Background\naxile loading is produced by two or more collinear forces acting along the bloc of a long flimsy appendage, such as mild mild steel restriction shown in Figure A. th is casing of loading occurs in numerous engineering elements, including man-to-man members that fuddle up machine, bridge and make trusses. When a structure member or machine divisor is subjected to the external forces (applied loads and behave reactions), internal resisting forces will let within the member or component to balance the external forces. In the simplest qualitative terms, stress is the intensity of internal force on the cross-sectional subject field of a trunk. In this test, the distribution of internal force has a resultant force that is popular to exposed cross-sectional cranial orbit of a simple bar. Thus,\nWhen the axial loading is applied to the body, individual points of the body generally work with the direction of the external force. This hunting expedition of points is generally known as displacement (vector quantity) that will posit a translation and/or rotation of the body as a whole and uncomplete the size nor the shape of the body is cha nged. The change in any(prenominal) dimension associated with these displacements is known as deform...
