A torque of 22 lb·in. is applied to one end of a 5-in.-long composite shaft that consists of two polymer tubes. The outer tube has a polar moment of inertia of 0.046 in.4 and a shear modulus of 180 ksi. The inner tube has a polar moment of inertia of 0.00687 in.4 and a shear modulus of 175 ksi. Determine the magnitude of the torque produced in the inner tube.

A steel [E = 30,400 ksi, G = 11,700 ksi] socket extension (2) has a diameter of 0.62 in. and a length of L = 1.3 in. It connects socket (3) to ratchet handle (1) which is 8.6 in. long. If a perpendicular force of 24.0 lb is applied to the end of the ratchet handle, determine the maximum shear stress in the socket extension.
