1.The foot pedal on hydraulic brake system exerts a force of 60.0 lbs on a piston with a diameter of 0.500 cm. in the master cylinder. The brake fluid in the brake system transmits the pressure from the master cylinder to a brake pad cylinder piston with a diameter of 3.50 cm.
a.What is the pressure of the foot pedal on the piston in lb/in2 and Pascals?
b.What is the force exerted by the brake pad piston in Newtons?
