a.) Calculate the moment of inertia of the rim about the axle.

b.) Determine the moment of inertia of any one spoke, assuming it to be a long, thin rod that can rotate about one end.

c.) Find the total moment of inertia of the wheel, including the rim and all 50 spokes.

a. The moment contribution of the rim is

Irim = Mrim * R^2

b. The moment contribution of one spoke is

Ispoke = (Mspoke*R^2)/3

c. Add them up. Remember to multiply the single spoke contribution by 50.
