A tоrque оf 26 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 0.037 in.4 and a shear modulus of 170 ksi. The inner tube has a polar moment of inertia of 0.00779 in.4 and a shear modulus of 180 ksi. Determine the magnitude of the torque produced in the inner tube.
