A uniform, 0.0350 kg rod of length 0.450 m rotates in a horizontal plane about a fixed axis through its center and perpendicular to the rod. Two small rings, each with mass 0.0200 kg, are mounted so that they can slide without friction along the rod. They are initially held by catches at positions 0.0550 m on each side of the center of the rod, and the system is rotating at 48.0 rev/min. With no other changes in the system,...

A uniform wire of mass M and length d rotates in a horizontal plane about an axis passing through its center. Two small beads, each of mass m, are placed on the wire; friction between the beads and the wire is negligible. The beads are initially held on the wire by catches at a distance d/4 on either side of the center, and the system rotates with angular speed ω0. The catches are then released, and the beads slide outward...

A 54-cm-long, 500 g bar rotates in a horizontal plane on an axle that passes through the center of the bar. Compressed air is fed in through the axle, passes through a small hole down the length of the bar, and escapes as air jets from holes at the ends of the bar. The jets are perpendicular to the bar's axis. Starting from rest, the bar spins up to an angular velocity of 200 rpm at the end of 12...
