Question

Give reason for the following:
 In a single fixed pulley, the velocity ratio is always more than the mechanical advantage.

Solution

In a single fixed pulley, some effort is wasted in overcoming friction between the strings and the grooves of the pulley; so the effort needed is greater than the load and hence the mechanical advantage is less than the velocity ratio.

  Is there an error in this question or solution?
