Question

Find the moment of inertia of system passing about one of its diagonal

Answer 1

Answer:

M.I about an axis parallel to one side and intersecting other side at mid-point is (m×l^2)/12 . Similarly for the other axis perpendicular to this is same due to symmetry of square. Therefore by applying perpendicular axis theorem the M.I of the square along an axis perpendicular to plan of square is (m×l^2)/6.

Answer 2

Answer:ml^2/12
