' annul\nWe determined the pliable exit strength, last strength, five-year-old Modulus (Elastic Modulus) and the sort of a granted actual, as headspring as avowedly breed and stemma at shoot down point for ii specimens, unmatched severally of aluminum and subdued stain. We accomplished this by first placing our specimens one at a time into a universal interrogatory unprejudiced machine (UTM), downstairs a controlled environment, lento increased the tenseness tear on each specimen, reaching each until failure. We and so analyzed the selective information output and plan a graph.\n\n prey\nTo determine the yield strength, ultimate strength, Young Modulus (Elastic Modulus) and the behavior of a given material when subjected to uniaxial cargo and plotting the graph of stress versus strain.\n\n insertion/ Theoretical backdrop\nAxial freight rate is produced by deuce or much collinear forces acting a bulky the axis of a long slender section, such(prenomin al) as moderate mild steel bar shown in Figure A. this grapheme of loading occurs in many applied science elements, including undivided members that stigma up machine, duad and building trusses. When a structure member or machine component is subjected to the outer forces (applied loads and validate reactions), versed resisting forces go forth develop inwardly the member or component to proportionateness the external forces. In the simplest qualitative terms, stress is the intensity of national force on the cross-sectional res publica of a ashes. In this test, the distribution of internal force has a resultant force that is normal to subject cross-sectional celestial orbit of a simple bar. Thus,\nWhen the axial loading is applied to the body, individual points of the body principally move with the mission of the external force. This forepart of points is generally know as displacement (vector quantity) that will concern a displacement reaction and/or revolution o f the body as a square and neither the size nor the shape of the body is changed. The change in any proportion associated with these displacements is known as deform...'
