Question

difference between fixed pulley and movable pulley?

Answer 1

Explanation:

A good example of a fixed pulley is a flag pole: When you pull down on the rope, the direction of force is redirected by the pulley, and you raise the flag.

4. The weight of pulley itself does not affect its mechanical advantage. 4. The weight of pulley itself reduces its mechanical advantage.

5. It is used to change the direction of effort. 5. It is used as force multiplier.
