Mounted on a low-mass rod of length 0.32 m are four balls (Figure 11.77). Two balls (shown in red on the diagram), each

of mass 0.82 kg, are mounted at opposite ends of the rod. Two other balls, each of mass 0.29 kg (shown in blue on the

diagram), are each mounted a distance 0.08 m from the center of the rod. The rod rotates on an axle through the center of

the rod (indicated by the “x” in the diagram), perpendicular to the rod, and it takes 0.9 seconds to make one full rotation.
