Bending Stress A cantilever beam of length 1.1 m carries a uniformly distributed load w, as shown in Figure QI (a). The beam is made from a circular hollow section with an inner radius of R, = 50 mm and a thickness of t= 10 mm (refer to Figure Q1 (b)). The maximum allowable longitudinal stress of the beam is 150 MPa. W L Figure Q1 (a) B Figure Q1 (b) (a) Determine the reactions. (b) Draw the shear force and bending moment diagrams, indicating key values. (c) Compute second moment of area and elastic section modulus (d) Calculate the maximum permissible uniformly distributed load. (e) Draw the bending stress distribution across the section at fixed end.

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.
