Question

Moment of inertia of a uniform quarter disc of radius R and mass M about an axis through its centre of mass and perpendicular to its plane is, MR 2 2 - M 4 R 3 π 2, MR 2 2 - M 2 4 R 3 π 2, MR 2 2 - M 4 R 2 π 2, MR 2 2 + M 2 4 R 3 π 2 9 32 π

MARKS App · Accepted Answer

Moment of Inertia of the object about O is MR 2 2 By parallel axis theorem MR 2 2 = I cm + M 4 R 3 π 2 2 I cm = MR 2 2 - M 2 4 R 3 π 2
