The single-plate clutch in the figure has friction linings on both faces of the plate, with the outer and inner radii shown. The clamping force is supplied by the springs listed in the figure, μ = 0.30, and the engine runs at 2400 rpm. Assuming uniform wear, determine (a) the maximum torque the clutch can transmit (answer in N·m), (b) the corresponding power (answer in kW) and (c) the maximum intensity of pressure on the lining (answer in MPa).
