Multiple Choice

The brake pedal is very small but the driver is able to stop the car because when pressing on the pedal 

• the pressure is exerted evenly through the fluid to all 4 brake pads.
• Pascal's principle is being demonstrated.
• this is hydraulics in action!
• all of these options.

Multiple Choice

According to Pascal’s principle, in a hydraulic system a pressure exerted on a piston produces an equal increase in pressure on another piston in the system. If the second piston has an area 10 times that of the first, the force on the second piston is 10 times greater, though the pressure is the same as that on the first piston.

• True
• False

Multiple Choice

State the formula for calculating pressure using Pascal's principle.

• P = F/A

• P = F*d

• P = F/m

• P = F/V
