A hydraulic brake system is shown. The area of the piston in the master cylinder is
6.35 cm2, and the area of the piston in the brake cylinder is 1.72 cm2. The coefficient of
kinetic friction between the brake shoe and the wheel drum is 0.453. How large is the frictional force between the brake shoe and the wheel drum when a force
of 46 N is exerted on the pedal? Answer in units of N.
