A composite shaft is comprised of an inner solid steel shaft 1/6 ft in diameter slipped over with a hollow bronze shaft of 1/4 ft outer dimater and 1/6 ft  inner diameter and of the same length as the steel shaft. The two shafts are then fastened rigidly together at their ends. For steel, G = 12 × 106 psi, and for bronze, G = 6 × 106 psi. What torque can be applied to the composite shaft without exceeding a shearing stress of 12,000 psi in the steel or 8,000 psi in the bronze?

Combined Loading

Any functioning component, such as machine parts, structural members, pressure vessels, and so on, are all under the influence of more than one force. When anybody is under the influence of more than one force such as shear forces, bending moments, axial forces, torsion, and so on, then such body is said to be under combined loading. A very practical example of combined loading is the crankshaft of an internal combustion engine (IC engine). The crankshaft of the IC engine is under high rpm, which is caused due to the torsional forces. Due to the presence of piston, counterbalances, and internal imbalances, the crankshaft experiences lateral forces and due to the rise in temperature, the crankshaft undergoes thermal expansion, which pulls the crankshaft along the axial direction and lateral direction. The presence of unbalanced loads along the periphery of the crankshaft also induces a bending moment.
