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

Solutions:

We must keep in mind that velocity ratio is 2 for a single movable pulley.

When a load is lifted down by a certain distance, the force used to lift it must be applied twice as far. This is because when any object attached to a pulley is lifted, force is applied to the ropes on opposite sides of the pulley. As one side rope moves upward and the other side rope moves downward by the same distance.

So, Velocity ratio = (distance travelled by Effort) / (distance travelled by Load) = 2

VR = x/ (distance travelled by Load) = 2

Distance travelled by Load = x/2
