A pulley system has a velocity ratio 5 . Draw a neat labelled diagram of the pulley system to lift a load by applying the effort in a convenient direction. Mark the tension in your diagram. If the efficiency of the system is $80 \%$ find its mechanical advantage.

Explanation

The correct pulley system is a combination of a fixed pulley and a movable pulley. The fixed pulley changes the direction of the effort, while the movable pulley changes the direction of the load. The tension in the system is marked as T.
