A circular disc of moment of inertia It is rotating in a horizontal plane about its symmetry axis with a constant angular velocity ωi. Another disc of moment of inertia Ib is dropped co-axially onto the rotating disc. Initially, the second disc has zero angular speed. Eventually, both the discs rotate with a constant angular speed ωf. The energy lost by the initially rotating disc due to friction.

A mass, m, moves in a circle on a smooth horizontal plane with velocity, V0, at a radius, R0. The mass is attached to a string which passes through a smooth hole in the plane as shown. The tension in the string is increased gradually and finally m moves in a circle of radius 2/R0. The final value of the kinetic energy is

Two discs of same moment of inertia rotating about their regular axis passing through centre and perpendicular to the plane of disc with angular velocities ω1 and ω2. They are brought into contact face to face coinciding the axis of rotation. The expression for loss coinciding of energy during this process is:
