Question

3. A multiple disc clutch has an outside diameter of 165 mm and inside diameter of 84 mm. The clutch material permits a maximum pressure of 262 kPa and has a coefficient of friction of 0.3. Determine (a) the actuating force, (b) the number of discs needed (c) actual maximum pressure, (d) Initially, the speed of driving side is 500 rpm and driven side is stationary. If the mass moments of inertia for driving side and driven side are 11-30 kg.m2 and I2-25 kg.m2, respectively, what is the engagement time? What would be the speed just after clutching? (e) For the case in (d), determine the total energy absorbed by the clutch assembly during engagement Uniform wear may be assumed and a torque of 350 Nm is to be transmitted
