A-LevelPhysicsForces, density and pressureOct/Nov 2016Paper 1 Q161 Mark
The diagram shows the brake system of a car. [Figure 16.1] The pipes are filled with incompressible liquid. When a force is applied to the brake pedal, the pressure in the liquid increases and applies a force to each of the four wheels. The area of the piston connected to the brake pedal is 8 cm². The area of each piston connected to the brakes is 12 cm². A force of 800 N is applied by the foot to the brake pedal. What is the force applied to each brake?
A300 N
B530 N
C1200 N
D4800 N
