Answer to Question #76027 in Mechanics | Relativity for GBSM

Question

A centrifugal clutch has four shoes shown in Figure 3, each of mass [m] 2kg which are
held on retaining springs of stiffness [S] 10kN/m. The internal diameter of the clutch drum
[D] is 600mm and the radius of the centre of gravity of the shoes when in contact with the
drum [r 0 ] is 250mm. The stationary clearance [x] between the shoes and the drum is
20mm and the coefficient of friction [μ] is 0.25.
Determine the performance of the rotating system due to the effects of centripetal
acceleration by finding the following:
(a) The rotational speed in revolutions per minute at which the clutch starts to engage;
(b) The torque and the power transmitted at a speed [ω] of 1500 rpm.
