Question

The mechanical advantage of an actual pulley is
less than 1 . give reason​

Answer 1

Explanation:

In an actual pulley due to friction, the mechanical advantage is less than 1 (i.e. the effort is more than the load). The reason for using the pulley when its mechanical advantage is equal to 1 or less than 1 is that the pulley allows us to apply the effort downwards i.e. in a convenient direction.
