Question 2 2.1. In manufacturing Engineering organizations, it is important to know the mechanical properties of materials before the material can be processed, describe three reasons why this is crucial (6) 2.2 A torsion test has a radius=40mm, wall thickness = 3mm and a gauge length of 60, a torque of 750 N-m resulting in an angular deflection of 0.4º. Determine the following: a) Shear stress. (3) b) Shear strain. (5) 2.3 A tensile test sample begins to neck at a true strain = 0.15 and true stress = 230 MPa. If no more information is provided, determine the strength coefficient and the strain-hardening exponent in the flow curve equation. Assume that n = ε when necking starts. (5) [19] ту 10] 2/5
