5-91. The A992 steel shaft is made from two segments. AC has a diameter of 0.5 in. and CB has a diameter of 1 in. If the shaft is fixed at its ends A and B and subjected to a uniform distributed torque of 60 lb.in./in. along segment CB, determine the absolute maximum shear stress in the shaft. 5 in. 0.5 in. 20 in. Prob. 5-91 60 lb-in./in. 1 in.
