You go to the gym to ride a stationary bicycle. The bicycle uses a large wheel to create resistance for your exercise. The wheel consists of some small spokes (we’ll ignore the spokes) and a hollow cylinder with an inner radius of 12cm, an outer radius of 35cm, and a mass of 48.9kg.

4) How much torque did you apply to the wheel?
With the bike’s wheel spinning at 36rad
s you decide to turn up the resistance to get a good workout.
5) If the bike is operated at a power level of 250W of resistance for 30 minutes, how much work will you
have done?
6) How much torque did you need to apply to the wheel to accomplish that workout?
