A 4-m long shaft transmits a torque of 5 kN-m. Determine the maximum torsional stress (TMax) of the given shaft using two approaches that are: (1) exact formula which considers the member as a circular hollow shaft and the (2) approximate formula which considers the 4 mm shaft as a thin-walled tube. Knowing that the first approach gives the exact value of the maximum torsional shearing stress, what is the percentage error of the shearing stress of the shaft using the approximate formula? 100 mm A. TMax using the exact formula (MPa) B. TMAX using the approximate formula (MPa) C. Percentage error (%)

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.
