A torque of 23 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 0.0312 in.4 and a shear modulus of 180 ksi. The inner tube has a polar moment of inertia of 0.00667 in.4 and a shear modulus of 160 ksi. Determine the magnitude of the torque produced in the inner tube.
