Question

derive an expression for moment of interia of square sheet about an axiz perpandicular to its plane​

Answer 1

Answer:

Moment of Inertia of a Square about its Diagonal

Moment of inertia about an axis parallel to one side and bisecting the other side at mid-point is (m×l2)/12. ... Hence, by using the perpendicular axis theorem, the moment of inertia of the square through an axis perpendicular to the plane of the square is (m×l2)/6.
