he compound shaft is attached to a rigid wall at each end. For the bronze segment AB, the diameter is 75 mm and G = 35 GPa. For the steel segment BC, the diameter is 50 mm and G = 83 GPa. Given that a = 2 m and b = 1.5 m, compute the largest torque T in kN-m that can be applied as shown in the figure if the maximum shear stress is limited to 60 MPa in the bronze and 80 MPa in the steel.
A flange-and-bolt coupling between two shafts carries 12 bolts at a pitch diameter of 18 in. The shafts carry a torque of 50,000 ft-lb. Assuming that this torque is transmitted by shear across the 12 bolts and that these bolts are to be designed for a shear stress s3 = 3,000 lb/sq in., what is the bolt diameter?
