A bicycle wheel has a diameter of 64.8 cm and a mass of 1.90 kg. Assume that the wheel is a hoop with all of the mass concentrated on the outside radius. The bicycle is placed on a stationary stand and a resistive force of 116 N is applied tangent to the rim of the tire. (a) What force must be applied by a chain passing over a 9.04-cm-diameter sprocket in order to give the wheel an acceleration of 4.55 rad/s? N (b) What force is required if you shift to a 5.58-cm-diameter sprocket? KN Need Help? Read
