Two lightweight rods $24cm$ in length are mounted perpendicular to an axle and at $180$ to

each other. At the end of each rod is a $480-$g mass. The rods are spaced $42cm$ apart along

the axle. The axle rotates at $4\mathrm{.}6ra\frac{d}{s}.($Figure $1)$

What is the component of the total angular momentum along the axle?
