A fоrce оf P = 28 N is аpplied tо а lever аt the end of a composite shaft. Sleeve (1) has a polar moment of inertia of 124,000 mm4 and a shear modulus of 1.2 GPa. Core (2) has a polar moment of inertia of 23,000 mm4 and a shear modulus of 0.5 GPa. Determine the torque produced in sleeve (1). Let a = b = 230 mm.
