Identify and describe the concepts, which are fundamental to velocity ratio. If the mechanical advantage and the velocity ratio of a machine are compared, then the efficiency of the machine can be determined. It is usually expressed as a percentage (%). Complete the formula: % Efficiency, ( = _____ x _____
