The shaft of a hand operated wire rope hoist is supported on bearings A and B. The shaft is keyed to the drum of diameter of 200mm and the wire rope is turned around it. A tangential load of 4500 N is applied at the end of the rope. The yield stress for the shaft material is taken as 310 MN/m?. a. Calculate the maximum and minimum principal stresses in the shaft b. Calculate the required shaft diameter d based upon Tresca theory of failure using a factor of safety of 3 c. Determine the factor of safety for the shaft diameter d as obtained in (b) above based upon von-Mises theory of failure. Comment on the value obtained
