nip\nWe checkd the elastic acquit strength, ultimate strength, spring chicken Modulus (Elastic Modulus) and the manner of a inclined material, as well as truthful stress and strain at rupture point for deuce specimens, one each of aluminium and daft steel. We accomplished this by first placing our specimens one at a time into a universal testing machine (UTM), under a controlled environment, easy increased the tension long suit on each specimen, reach each until failure. We then examine the data output and plot 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 effect and plotting the graph of stress versus strain.\n\nIntroduction/ theoretic Background\nAxial freight is produced by two or more collinear forces performing along the axis of a long slender member, such as mild mild steel bar shown in Figure A. this type of shipment occurs in many pl an elements, including individual members that make up machine, bridge and building trusses. When a structure member or machine piece is subjected to the outside forces (applied loads and support reactions), inseparable resisting forces will develop indoors the member or component to balance the external forces. In the simplest qualitative terms, stress is the military capability of sexual force on the cross-sectional area of a automobile trunk. In this test, the distribution of internal force has a final result force that is normal to candid cross-sectional area of a simple bar. Thus,\nWhen the axial loading is applied to the body, individual points of the body slackly move with the wariness of the external force. This movement of points is generally known as deracination (vector quantity) that will involve a translation and/or rotation of the body as a whole and neither the size of it nor the shape of the body is qualifyingd. The change in any holding associated wi th these displacements is known as deform...
