The Wheels of a standard bicycle have a rolling radius of approximately 15 inches and a radius to the center of the caliper disk brake pads of 13.5 inches. The combined weight of the bike plus the rider is 260 lb, which is equally distributed between the wheels. If the coefficient of friction between the tires and the road surface is twice that between the brake pads and the metal wheel rim, what clamping force must be exerted by the calipers in order to slide the wheels? Ans. Fc 144.4 lb
