Give two reasons why the efficiency of a single movable pulley system is not 100%.

Solutions:

Because of the following factors, the efficiency of a single movable pulley system is not 100 percent.

(i) The pulley bearing friction is not zero.
(ii) The pulley and string do not have the same weight.

i
