A force of P = 24 N is applied to a lever at the end of a composite shaft. Sleeve (1) has a polar moment of inertia of 92,800 mm4 and a shear modulus of 1.8 GPa. Core (2) has a polar moment of inertia of 38,300 mm4 and a shear modulus of 0.7 GPa. Determine the torque produced in core (2). Let a = b = 240 mm.

A force of P = 27 N is applied to a lever at the end of a composite shaft. Sleeve (1) has a polar moment of inertia of 56,500 mm4 and a shear modulus of 1.0 GPa. Core (2) has a polar moment of inertia of 23,000 mm4 and a shear modulus of 1.5 GPa. Determine the torque produced in core (2). Let a = b = 230 mm.

A 38-lb cardboard box sits on an oak beam. Determine the maximum bending moment in the beam if the weight is modeled as distributed load w = 1.4615 lb/in. Let a = 40 in. and b = 26 in.
