Answer 1

This simple pulley allows the man to lift the box with less effort by reducing the amount of force needed to lift the box.

Answer 2

so it changes the direction of the force needed to lift the box?

Answer 3

Yes, the pulley changes the direction of the force needed to lift the box. Instead of lifting the box directly upward with a lot of force, the person can pull down on the rope with less force and still lift the box due to the mechanics of the pulley.
