A circular hole of radius `r//2` is cut from a circular disc of radius `'r'`. The disc lies in the `xy` plane. Determine the moment of inertia about an axis passing through the centre and perpendicular to the plane of the disc.

The moment of inertia of a circular disc about an axis passing through the circumstances perpendicular to the plane of the disc is

The moment of inertia of a copper disc, rotating about an axis passing through its centre and perpendicular to its plane

A disc of radius R has a concentric hole of radius R /2 and its mass is M. Its moment of inertia about an axis through its centre and perpendicular to its plane, is

Calculate the moment of inertia of a disc of radius R and mass M, about an axis passing through its centre and perpendicular to the plane.

A disc has mass 9 m. A hole of radius R/3 is cut from it as shown in the figure. The moment of inertia of remaining part about an axis passing through the centre 'O' of the disc and perpendicular to the plane of the disc is :

From a circular disc of mass M and radius R , a part of 60^(@) is removed. The M.I. of the remaining portion of disc about an axis passing through the center and perpendicular to plane of disc is

A circular hole of radius R//2 is cut from a circular disc of radius R . The disc lies in the xy -plane and its centre coincides with the origin. If the remaining mass of the disc is M , then a. determine the initial mass of the disc and b. determine its moment of inertia about the z -axis.
