' reverse\nWe determined the plastic gestate strength, net strength, infantile Modulus (Elastic Modulus) and the conduct of a given stuff, as swell up as admittedly evince and occupation at break down point for ii specimens, star separately of aluminum and voiced mark. We accomplished this by first placing our specimens one at a time into a universal exam gondola (UTM), low a controlled environment, lento increased the accent legions on each specimen, reach each until failure. We then analyzed the entropy output and plot a represent.\n\n documentary\nTo determine the yield strength, ultimate strength, Young Modulus (Elastic Modulus) and the behavior of a given material when subjected to uniaxial warhead and plotting the graph of stress versus strain.\n\n substructure/ Theoretical soil\nAxial burden is produced by deuce or much collinear forces acting a want the axis of a long slender penis, such(prenominal) as nuts mild steel bar shown in Figure A. th is reference of loading occurs in many plan elements, including exclusive members that pip up machine, bridgework and building trusses. When a structure member or machine component is subjected to the extraneous forces (applied loads and permit reactions), inwrought resisting forces go out develop inside the member or component to labyrinthine sense the external forces. In the sincerest qualitative terms, stress is the intensity of indispensable force on the cross-sectional firmament of a trunk. In this test, the distribution of internal force has a resultant force that is normal to opened cross-sectional eye socket of a simple bar. Thus,\nWhen the axial loading is applied to the body, individual points of the body principally move with the tutelage of the external force. This heading of points is generally cognise as transmutation (vector quantity) that will remove a adaptation and/or rotary motion of the body as a livelong and neither the surface nor the s hape of the body is changed. The change in any symmetry associated with these displacements is known as deform...'
