Concept explainers

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.

Please help. This problem involves torsional stress and strain. Thank you.
The hollow cylinder shaft shown in the figure has an inside diameter of 15mm and the gears are subjected to the indicated load. The bearings at points A and B only exert forces on the shaft in the y and z directions. If the allowable shear stress is known to be operm = 70 MPa. Use the maximum shear stress theory of failure and proceed to:a) Draw the bending moment diagrams My and Mz and torque T, determine the magnitude and location of the absolute Maximum Moment.b) Determine the outer diameter of the shaft to within 1 mm.
