Solutions to HC Verma's Concepts of Physics :: PART II

Rotational Mechanics – HC Verma’s Concepts of Physics – Solution

HC Verma’s Concepts of Physics - Chapter 10 - Question 15
Find the moment of inertia of a uniform square plate of mass m and edge a about one of its diagonals.
The question was posted by Ankit
Solution:
Let the moment of inertia about the axis through the centre of the square plate perpendicular to the plane, assumed to be along Z axis, be I. Now the square plate will be in the XY plane. Let the X axis and Y axis be parallel to the edges and passing through the centre.
Then, we know that Ix = Iy = ma2/12
Then, according to perpendicular axis theorem,
