The shaft shown in the figure below and rotating at a speed of 1 radian / sec transmits 9 kW of power from the gear at the B point to the pulley at the D point. Manufactured from cold drawn AISI 1040 steel, the shaft is machined to the given dimensions and bedded from A and C points. The highest working temperature of the spindle is 50 ° C. At point D; Since (d2 / d3 = 1.1) and (r /d = 0.1), determine the diameter d3 of the shaft using Goodman's theory. (kb = kc = kf = 1, q = 0.8 and qs = 0.9) 200 mm 140 mm

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.
