... The input work is the input force multiplied by the length of the ramp (10 meters). If you set the input work equal to the output work, you quickly find that the input force is 50 newtons (Fd = F × 10 m = 500 J). The input force is one-tenth of the output force. For a frictionless ramp, the mechanic ...
