Question

Each of the slender rods of length l and mass m is welded to the circular disk which rotates about the vertical z-axis with an angular velocity $\omega$. Each rod makes an angle $\beta$ with the vertical and lies in a plane parallel to the y-z plane. Determine an expression for the angular momentum $H_O$ of the two rods about the origin O of the axes.

Step 1

1 of 5Since the disk rotates about $z-$axis at the rate $\omega_z=\omega\;\textbf{k}$, thus $\omega_x=\omega_y=0$, referring to equation (7-11) the angular momentum of the two rods about the origin $O$ is

$\begin{align*} H_O&=(-I_{xz}\;\omega_z)\;\textbf{i}-(I_{yz}\;\omega_z)\;\textbf{j}+(I_{zz}\;\omega_z)\;\textbf{k}\tag{1}\\ \end{align*}$
