A bicycle wheel has a diameter of 57.7 cm

and a mass of 2.66 kg. The bicycle is placed

on a stationary stand and a resistive force of

156 N is applied tangent to the rim of the tire.

Assume that the wheel is a hoop with all of

the mass concentrated on the outside radius.

In order to give the wheel an acceleration of

4.67 rad/s

2

, what force must be applied by a

chain passing over a 3 cm diameter sprocket?

Answer in units of N
