Q2) A plate clutch has 3 discs on the driving shaft and 2 discs on the driven shaft providing 4 pairs of contact surfaces (8 contact surfaces) each of 240 mm external diameter and 120 mm internal diameter. Assuming uniform pressure (P=constant). See figure (Q2) below. a) Find the total springs load pressing the plates to transmit 25 KW at 1575 rpm, taking μ=0.3 b) If there are 6 springs each of stiffness 13 KN/m and each of contact surface has worn away by 1.25 mm. What is the maximum power that can be transmitted if the same speed and µ? discs (driving)

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.
