WebbCalculate the efficiency of a bicycle if the input work to the turn the pedals is 100 J and the output work is 40 J. Efficiency = Output Work/Input Work x 100 % force distance … WebbThe efficiency output of a machine is simply the output work divided by the input work, and is usually multiplied by 100 so that it is expressed as a percent. % efficiency = Wo Wi × 100 Look back at the pictures of the simple machines and think about which would have the highest efficiency.
