How to calculate useful work done
WebHow do you calculate useful work done? You can calculate the energy transferred, or work done, by multiplying the force by the distance moved in the direction of the force. How do you calculate useful output? Hence or otherwise, calculate the efficiency of the motor. WebWork W = force * displacement Power P = W/T Where, W is the work done T is the time P is the power Example Question: An electric machine makes use of 500 J of energy to do work in 25 sec. How much does it use? Solution: Given that Work done W = 500 J Time T = 25 sec The power formula is Power = Work/Time P = 500/25 = 20
