The diagram shows a movable pulley system. When moving a load, this pulley system changes the —

• direction of the force.
• amount of force needed.
• pull of gravity on the load.
• overall mass of the rope.

The diagram provided shows a fixed pulley system.  A fixed pulley does not change the amount of effort needed to lift the load, but it does change the 

• direction of the force.
• weight of the load.
• volume of the force.
• shape of the load.

The diagram shown is a fixed pulley, what amount of force would you need to apply to the rope to lift the 200 N load?

• 200 N

• 100 N

• 400 N
