The device shown in Fig. rotates on the vertical axle as shown. The frame has negligible mass as compared to the four masses each of mass `m`. Initial angular velocity of the system is `omega_(0)`. Due to an internal mechanism the spokes in the frame lengthen so that the radii of the masses become `2a`. Initially, it was a. What will be the new angular velocity of the system?

A circular disc of mass M and radius R is rotating with angular velocity omega . If two small spheres each of mass m are gently attached to two diametrically opposite points on the edge of the disc, then the new angular velocity of the disc will be

A disc of mass M and radius r is rotating with an angular velocity omega . If gently, two masses m each are placed at a distance r//2 on either side of the axis of rotation, what will be the new angular velocity ?

A smooth uniform rod of length L and mass M has two identical beads of negligible size each of mass m which can slide freely along the rod. Initially the two beada are at the centre of the rod and the system is rotating with an angular velocity omega_0 about an axis perpenducular to the rod and passing through the midpoint of the rod. There are no external forces. When the beads reach the ends of the rod, the angular velocity of the system is ......
