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.

Link AB, of width b = 2 in. and thickness t = 1414 in., is used to support the end of a horizontal beam. The average normal stress in the link is -18 ksi and the average shearing stress in each of the two pins is 12 ksi. Determine the average bearing stress (ksi). **The way I had solved it was that I used the given normal stress to first find the P force needed to plus into my bearing stress formula. I still however need the diameter. The answer key says to use the given shear stress equation to find the diamter, how do you know to use that and not the shear stress formula again?
