Question

In a single movable pulley, if the effort moves by a distance x upwards, by what height is the load raised?

• A. $\frac{x}{5}$
• B. $\frac{x}{4}$
• C. $\frac{x}{2}$
• D. $\frac{x}{8}$

Answer 1

The correct option is C

$\frac{x}{2}$

In a movable pulley, the axle is not fixed to any rigid support. The pulley can move up and down. The effort is applied in the same direction as the load is lifted. In a movable pulley, we ned to pulll twice the length of the rope. It reduces the effort needed to lift a weight by half. If the effort moves by a distance x upwards, the load moves up by $\frac{x}{2}$.
