MCQ
A movable pulley is used as : ________ .
- ✓a force multiplier
- Ba speed multiplier
- Ca device to change the direction of effort
- Dan energy multiplier
✓
Answer
Correct option: A.
a force multiplier
Force multiplier
Explanation: The mechanical advantage of movable pulley is greater than 1. Thus, using a single movable pulley, the load can be lifted by applying an effort equal to half the load (in ideal situation), i.e. the single movable pulley acts as a force multiplier.
