A uniform circula disc has radius R and mass m. A particle also of mass m, is fixed at a point A on the edge of the disc as shown in figure. The disc can rotate freely about a fixed horizontal chord PQ that is at a distance R/4 from the centre C of the disc. The line AC is perpendicular to PQ. Initially, the disc is held vertical with the point A at its highes position.

A uniform circular disc has radius R and mass m . A particle, also of mass m , if fixed at a point A on the edge of the disc as shown in the figure. The disc can rotate freely about a horizontal chord PQ that is at a distance R//4 from the centre C of the disc. The line AC is perpendicular to PQ . Initially the disc is held vertical with the point A at its highest position. it is then allowed to fall, so that it starts rotation about PQ. Find the linear speed of the particle as it reaches its lowest position.

A uniform circular disc has radius R and mass m . A particle also of mass m is fixed at a point A on the wedge of the disc as in fig. The disc can rotate freely about a fixed horizontal chord PQ that is at a distance R//4 from the centre C of the disc. The line AC is perpendicular to PQ . Initially the disc is held vertical with the point A at its highest position. It is then allowed to fall so that it tarts rotating about PQ . Find the linear speed of the particle at it reaches its lowest position. .

The moment of inertia of a uniform circular disc of radius R and mass M about an axis passing from the edge of the disc and normal to the disc is.

The moment of inertia of a uniform circular disc of radius R and mass M about an axis passing from the edge of the disc and normal to the disc is.

From a uniform circular disc of radius R and mass 9M, a small disc of radius (R )/(3) is removed as shown in the figure. The moment of intertia of the remaining disc about an axis perpendicular to the plane of the disc and passing through centre of the disc is

A quarter disc of radius R and mass m is rotating about the axis OO' (perpendicular to the plane of the disc) as shown. Rotational kinetic energy of the quarter disc is
