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.

• Identify where in the cross section the max shear will occur.
Determine the thickness of the cross-section at the location you wish to find
shear stress.
• Calculate the Ix for the shape (assume bending in the x with most basic beams).
• Calculate Q by dividing the section into two pieces at the point you want shear
stress. Select one of the pieces (either will work), I picked the top piece.
Use the Shear Stress equation to determine the requested stress.
Compare you answer: Max shear stress = at the center of the cross section.
