actual MA= 3/1
theoritical MA= 4/1
efficiency=3/4
A machine with an efficiency of 100% is said to be efficient.
a) If a lever has a distance of 4m from the pivot to where a load of 500N is applied and a distance of 1m from the pivot to where the load is,calculate the efficiency of the lever when height moved by effort i 3m and height moved by load is 1m
