A hydraulic brake system in a car connects the brake pedal to the brakes on the wheels. When the driver presses the brake pedal inside the car, a piston applies force to a master cylinder containing hydraulic fluid. A hose connects the master cylinder to each brake cylinder. At each brake cylinder, hydraulic fluid pressure on a piston applies force to the brake shoe. Suppose that a driver applies a force of 250 N to the master cylinder, which has a diameter equal to cylinder. What is the force Fapplied by the brake cylinder on the brake shoe? F = the diameter of the brake N
