Question

In which direction the force must be applied, when a single pulley is used with a mechanical advantage greater than one?

• A. Downward direction
• B. Upward direction
• C. Both the direction
• D. Can be any random direction

Answer 1

The correct option is A

Downward direction

Mechanical advantage greater than one can be obtained by using single movable pulley by applying the force in the upward direction but it is inconvenient, so a fixed pulley is also used along with the movable pulley and force is applied in the downward direction.
