Question

Difference between single pulley and movable pulley

Answer 1

Answer:

A single fixed pulley is defined as a pulley with its axis of rotation fixed in place. It's used to shift the effort's direction. Whereas, a movable pulley is one that can move up and down and is connected to a ceiling or another object by two lengths of the same rope.

Answer 2

Difference between single pulley and movable pulley

single pulley -

• It is fixed to a rigid support.
• Its mechanical advantage is one.
• Its velocity ratio is one.
• The weight of the pulley itself does not affect its mechanical advantage.
• It is used to change the direction of effort.

Movable Pulley

• It is not fixed to a rigid support.
• Its mechanical advantage is two.
• Its velocity ratio is two.
• The weight of the pulley itself reduces its mechanical advantage.
• It is used as a force multiplier.
