(a) Name two (2) Failure Criteria that are suitable for ductile material. (1 mark) (b) A steel bar with 50 mm diameter is fixed at one end and loaded with a point load of 5 kN and a torque of 0.5 kN.m at its free end as shown in Figure Q1. The steel has E-200 GPa, G-80 GPa, v=0.3, yield=250 MPa i. ii. Sketch the stress elements at A, B, and C and label the stresses values. (4 marks) Determine if the bar material would yield, based on von Mises Failure Critereon with a safety factor of 1.5.
