O A solid shaft made of steel with yield stress of 280 MPa, is 45 mm in diameter and carries a tensile force of F = 100 kN. If the safety factor for the design of the shaft is 1.2, and assuming no misalignment. (i) (ii) Determine the torque, "T", required to initiate yielding according to Tresca yield criterion. (5 marks) Determine the torque, "T", required to initiate yielding according to Von Mises yield criterion. (7 marks) O Owing to the misalignment of the tensile force, the shaft yielded and was discovered that the line of application of the tensile force was offset from the parallel axis of the shaft, as shown in Figure 1. Calculate the amount of eccentricity 'e' which must have occurred to cause yielding of the shaft according to the Von Mises yield criterion. (13 marks) F=100KN T e Figure 1 F=100KN T
