Front

Explain why the ideal mechanical advantage of a machine is always greater than the actual mechanical advantage.

Back

Because of friction and other losses

A pulley system has an ideal mechanical advantage of 5. If the resistance force is 100 N, what is the effort force required?

Back

20 N

Describe how the resistance distance affects the mechanical advantage of a lever.

Back

Longer resistance distance decreases mechanical advantage.
