The solid circular shaft shown (Figure 1) has diameter 54 mm and length L₁ = 4.2 m. Let the positive axis point from A to B along the center of the shaft. A torsional load is applied a distance L₂ from the left end, as shown. The shear modulus is G = 55 GPa Part A - Torque with a known twist If the load is at L2 = 3.3 m and the angle of twist at C' is pc = 0.6 deg, what is the magnitude of the applied torque?

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.
