A wooden beam is fabricated by nailing together three boards as shown. The boards have dimensions of b1 = 11 in., d1 = 2.1 in., b2 = 2.1 in., d2 = 10 in., b3 = 6 in., and d3 = 2.1 in. (e) If a bending moment applied about the z axis produces a tension normal stress of σx = 580 psi at the bottom of the cross section, determine the compression normal stress produced at the top of the cross section.

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.
