There is a triangular plate as shown. A dotted axis is lying in the plane of slab. As the axis is moved downwards, moment of inertia of slab will first decrease then increase.
Reason: Axis is first moving towards its centre of mass and then it is receding from it.

Assertion : Two axes AB and CD are as shown in figure. Given figure is of a semi-circular ring. As the axis moves from AB towards CD, moment of inertia first decreases, then increases. Reason : Centre of mass lies somewhere between AB and CD.

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 :

The moment of inertia of a square plate of mass 4kg and side 1m about an axis passing through its centre and perpendicular to its plane is

Assertion: There is a thin rod AB and a dotted line CD. All the axes we are talking about are perpendicular to plane . As we take different axes moving from A to D, moment of inertia of the rod may first decrease then increase. Reason: Theorem of perpendicular axis cannot be applied here.

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.

In the figure shown find the moment of inertia of square plate having mass m and sides a. About an axis 2 passing through point C (centre of mass) and in the plane of plate?
