How to calculate useful work done

WebThe fundamental unit of work is one Newton-meter, or a joule (J). That is, applying a force of one Newton for one meter performs one joule of work. In Imperial units (as used in the United States), force is measured in pounds (lb) and distance is measured in feet (ft), hence work is measured in ft-lb. Mass vs. Weight WebState the equation for efficiency of a simple machine, % efficiency = W o W i × 100, and calculate Wo and Wi. Both work values are the product Fd. Discussion Efficiency in real machines will always be less than 100 percent because of work that is converted to unavailable heat by friction and air resistance.
