1. (a) (b) () A torque of M = 10 KN m is applied to a circular shaft. This produces the condition of pure shear" such that the shear stress 7 = MR/Iwhere R is the radius and Ip = R/2. If the ultimate tensile strength of the shaft is 600 N/m. Take E= 200KN/m; v = 0.3 and yield stress = UTS/2. Determine the radius of the shaft to avoid yielding using:- Maximum shear stress theory, Maximum stress theory (7 marks) (6 marks) Maximum strain theory (7 marks)
