A tоrque оf 25 lb·in. is аpplied tо one end of а 7-in.-long composite shаft that consists of two polymer tubes. The outer tube has a polar moment of inertia of 0.0325 in.4 and a shear modulus of 165 ksi. The inner tube has a polar moment of inertia of 0.00169 in.4 and a shear modulus of 190 ksi. Determine the magnitude of the torque produced in the inner tube.
