A flywheel used to prepare earthenware pots is set into rotation at 100 rpm. It is in the form of a disc of mass 10 kg and radius 0.4 m. A lump of clay (to be taken equivalent to a particle) of mass 1.6 kg falls on it and adheres to it at a certain distance X from the centre. Calculate X if the wheel now rotates at 80rpm.

A horizontal disc is freely rotating about a vertcal axis passing through its centre at the rate of 125 r.p.m. A blob of wax of mass 50 gm falls on it and sticks to it at a distance of 10 cm from the axis. If the reslting frequency of rotation is 75 r.p.m, calculate the moment of inertia of the disc.

A circular disc of mass 10 kg and radious 0.2 m is set into rotation about an axis passing through its centre and perpendicular to its plane by applying torque 10 Nm. Calculate angular velocity of the disc that it will attain at the end of 6 s from the rest.

A flywheel is a mechanical device specifically designed to efficiently store rotational energy. For a particular machine it is in the form of a uniform 20 kg disc of diameter 50 cm, able to rotate about its own axis. Calculate its kinetic energy when rotating at 1200 rpm. Use pi^2 = 10 . Calculate its moment of inertia , in case it is rotated about a tangent in its plane.

A disc of mass 2 kg and radius 0.2 m is rotating about an axis passing through its centre and perpendicular to its plane with an angular velocity 50 rad/s. Another disc of mass 4 kg and radius 0.1m rotates about an axis passing through its centre and perpendicular to its plane with angular velocity 100 rad/s. If the two discs are coaxially coupled, then the angular velocity of the coupled system would be
