A fоrce оf P = 23 N is аpplied tо а lever аt the end of a composite shaft. Sleeve (1) has a polar moment of inertia of 46,900 mm4 and a shear modulus of 1.7 GPa. Core (2) has a polar moment of inertia of 32,600 mm4 and a shear modulus of 1.8 GPa. Determine the torque produced in sleeve (1). Let a = b = 235 mm.
