Homework Help: Physics

Posted by Trin on Wednesday, January 9, 2013 at 12:12am.

A car's brake system transfers pressure from the main cylinder to the brake shoes on all four wheels. The surface area of the main cylinder piston is 7.2 sq cm, and that of the piston in each individual brake cylinder is 1.80 sq cm. The driver exerts a 5.00 N force on the pedal. What is the pressure added to the liquid in the brake system? And the force exerted on each broke shoe?
The driver pushes the pedal moving the piston 2 cm in the main cylinder. How much does the piston move in each of the brake cylinders?
