Calculate the moment of inertia of a bicycle wheel 66.7 cm in diameter. the rim and tire have a combined mass of 1.25 kg. the mass of the hub can be ignored since it distance from the axis of rotation is so small.

Moment of inertia of the wheel = 0.139 kg m²

Explanation;

diameter of wheel=66.7 cm=0.667 m

radius=d/2 = 0.667/2=0.3335 m

The moment of inertia of a wheel is given by

i = m r²

m = mass of the wheel=1.25 kg

r = radius of wheel=0.3335 m

i = 1.25 (0.3335) ²

i=0.139 kg m²
