The ratio of the moment of inertia of a circular plate and that of a square plate for equal depth, is

less than one
equal to one
more than one
equal to 3π/16
none of these.

Correct Answer: equal to 3π/16

Explanation:

For circular plate, MI = π*d^4/64.

For square plate, MI = d^4/12.

So, Ratio = MI of circular plate/MI of square plate.

= 3*π/16.
