Question

Give reasons for using single fixed pulley.

✓

Answer

Single fixed pulley is used widely because:
(a) It is always easier to apply effort in the downward direction rather than in the upward direction. Thus, the pulley helps in changing the direction of effort.
(b) One can use one's own body weight, while applying the effort in the downward direction.
