Question

The moment of inertia of a square of side a about its diagonal is

Answer 1

You can use this four times with h = b = half the diagonal of the square. If length of the side of the square is a, second moment of area of the square with respect to one of its diagonals is . Second moment of area of a triangle about its base is bh^3/12, where is the base of the triangle and is its altitude.

Answer 2

Answer:

Explanation:

h = b = half the diagonal of the square. If length of the side of the square is a, second moment of area of the square with respect to one of its diagonals is . Second moment of area of a triangle about its base is bh^3/12, where is the base of the triangle and is its altitude.
