Figure P9.25 shows the essential parts of a hydraulic brake system. The area of the piston in the master cylinder is 1.75 cm2, and that of the piston in the brake cylinder is 6.4 cm2. The coefficient of friction between shoe and wheel drum is 0.50. If the wheel has a radius of 39 cm, determine the frictional torque about the axle when a force of 49 N is exerted on the brake pedal.
