Answer the following.

Mechanical Advantage = Output Force Mechanical Efficiency . Work Output X 100 Input Force Work Input Directions: Solve the following problems. Show all of your work and include the correct units. 1. You apply 200 N to a machine, and the machine applies 2,000 N to an object. What is the mechanical advantage? 2. What is the mechanical advantage of a wheel and axle that uses 50 Newtons of force to move a resistance of 2550 Newtons? a. What machine is being used to make the work easier? 3. Suppose you exert 15 N on a machine, and the machine exerts 300 N on another object. What is the machines mechanical advantage? 4. Which of the following makes work easier? A machine with a mechanical advantage of 15 or a machine to which you apply 15 N and that exerts 255 N? Why? 5. Which of the machines has a greater mechanical advantage? A machine to which you apply a force of 50N and the machine applies a force of 150N? Or the machine to which you apply a force of 60N and the machine applies a force of 200N? Why? 6. Tom uses 20 Newtons of force to move a wooden box with a resistance of 130 Newtons up a ramp. What is the mechanical advantage? a. What machine is Tom using to make the work easier
