Question

A wagon wheel is constructed as shown in the figure The radius of the wheel is 0.300m and the rim has mass 1.30kg. Each of the eight spokes, that lie along a diameter and are 0.300m long has mass 0.210 kg

What is the moment of inertia of the wheel about an axis through its center and perpendicular to the plane of the wheel?

Explanation / Answer

moment of inertia = 1.3*0.3*0.3 + (8*0.21*0.3*0.3/3) = 0.117 + 0.0504 = 0.1674 kgm^2
