    Question Clutch Question

    A multi plate clutch has 4 frictional surfaces, imternal diameter 120mm and external diameter 200mm. The coefficent of friction is 0.3

    What spring force will be required to transmit 20KW of power at 1440 RPM if the clutch is under uniform pressure conditions?

    The answer which I get is 1381.597N or 1.381KN (Please could someone confirm if this is correct?)

    Thanks,
