A tоrque оf 27 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 0.0268 in.4 and a shear modulus of 185 ksi. The inner tube has a polar moment of inertia of 0.00776 in.4 and a shear modulus of 160 ksi. Determine the magnitude of the torque produced in the outer tube.
