Example: Rotational Angular Momentum of a Bicycle Wheel
A bicycle wheel has a mass of 0.8kg and a radius of 32cm. If the wheel rotates in the xz plane, spinning clockwise when viewed from the +y axis, and making one full revolution in 0.75 seconds, what is the rotational angular momentum of the wheel?

Solution
The direction of $\vec{\omega}$ is -y.
$I = MR^{2} = (0.8kg)(0.32m)^2 = 0.082 kg \cdot m^2$
