The driver of a care presses the brake pedal. The lever-action of the pedal, along with the brake booster, translate this force into 110 pounds of force on the master cylinder. If the piston in the master cylinder has a bore of 0.600 inches, how much pressure is created in the brake system?
 
  What will be an ideal response?

Question 2

An airfoil, or wing creates downward force on the rear of a car for increased traction allowing air with elevated pressure to contact a large area, resulting in a force. Suppose an airfoil is subjected to a pressure of 0.25 psi, and 100 pounds of downward force are desired. How large, in square inches, should the airfoil be?
