Question

Moment of inertia of a square lamina of side 2a

Answer 1

Answer:

Now, coming to your question, let us first find the moment of inertia of the square plate about the center but parallel to it(say about the x-axis) .

Thus, its moment of inertia will also be (ma^2)/12, (mass is distributed at a distance a/2 from the axis) where m is the mass of the plate and a is its side length.

Answer 2

Answer:

The moment of inertia of a square laminaabout the perpendicular axis through its centre of mass is 20 kg per metre square then itsmoment of inertia about an axis touching its side and in the plane of the lamina.
