A hydraulic lift is used to raise a car. The area of piston B is ____ times the area of piston A. A downward force of FA is exerted on piston A resulting in a pressure of PA. The fluid at piston A is displaced downward a distance of dA.
Tap the blanks to accurately complete the following sentences.
As a result there is an upward force of FB on piston B, resulting in a pressure of PB that raises the car upward a distance of dB.
