# Basic Torque Question?

An automobile crankshaft transfers energy from the engine to the axle at the rate of 100hp(=74.6kW) when rotating at a speed of 1800 rev./min...What Torque (N~meters) does the crankshaft deliver?

Do I have to convert or is there a formula for this? Thanks! ~Dave

You will want to use: torque = power/angular velocity.

I would first convert your power to units of Newton meters per sec, and your angular velocity to radians per second, then simply plug the numbers into the equation above.
