A momentum wheel for dynamics class demonstration is show. It is basically a bicycle wheel modified with rim band-weighting, handles, and a pulley for cord startup. The heavy rim band causes the radius of gyration of the 3.1 kg wheel tobe 275 mm. If a steady 32 N pull F is applied to the cord, determien the angular acceleration of the wheel. Neglect bearing friciton.
