A uniform disc (of mass M and radius a) ...

A uniform disc (of mass `M` and radius `a`) has a hole (of radius `b`) drilled through it. The centre of the hole is at a distance `c` from the centre of the original disc. What is the moment of inertia of the disc about an axis through the centre of the disc and perpendicular to its plane ?

Text Solution

Verified by Experts

`(1)/(2)(M)/(a^(2)-b^(2))(a^(4)-b^(4)-2b^(2)c^(2))`
