Question

State whether the following statement is True or False.

The velocity ratio of a single moveable pulley is always $2$.

• A. True
• B. False

Answer 1

The correct option is A True

In this arrangement, the block is not fixed but carries the load. An inextensible string is wound round the groove and its one end is fixed to a fixed support while other end kept free to apply the effort. When the effort is applied, the block together with the load moves upwards.

Velocity Ratio (V.R)=Distance moved by the effort / Distance moved by the load = 2/1=2
