## Physics: Principles with Applications (7th Edition)

The angular velocity $\omega$ is the same for the rod and the small masses. To find the angular momentum, find the moment of inertia and multiply by the angular velocity. $$L=I \omega$$ $$L=(\frac{1}{12}M\mathcal{l}^2+2m(\frac{\mathcal{l}}{2})^2) \omega$$
