Question 1 (Together): You apply a force of 15 newtons to a pulley, and the pulley exerts a force of 1,200 newtons. What is the mechanical advantage of the pulley?

Question 2 (On Your Own): You apply a force of 36 newtons to an inclined plane, and the inclined plane exerts a force of 9,000 newtons. What is the mechanical advantage of the inclined plane?

Question 3 (Together): A pulley has a mechanical advantage of 10.  What would the output force of the pulley be if you applied a force of 350 N to it?

Question 4 (On Your Own): A wedge has a mechanical advantage of 525.  What would the output force of the wedge be if you applied a force of 500 N to it?
