Answer 2

Answer:

That means that the effort is more than the load

Explanation:

That a pulley allows us to apply downwards in a convenient direction. Directly upwards is difficult to raise a load. But with the help of pulley, the effort can be applied in the downward direction to move the load upwards,so one can hang on it to make use of his own weight also in order to apply the effort.
