Force transmitted by engine

  1. Oct 5, 2011 #1
    hi, I'm designing a clutch and need to calculate the force transmitted by the clutch. engine power is 30hp and rpm is 3000. How to calculate.

    You mean torque?

    power = torque * angular velocity.

    There may be peaks above that because of the non-constant torque produced by an engine.

    OK thanks bro.

    30 hp x (5252/3000 rpm) = 52.5 ft.lbs of torque.

    As mentioned, that may not be the torque peak of the engine, and the clutch also needs reserve capacity in order to resist slippage when applying the clutch at high loads.
