A column ABCD (2y₁ x 2y₂) of rectangular section carries a load P at Z having the co-ordinates (x, y) as shown in the given figure.
If the compressive streses are taken as positive and area A = 2y₁ x 2y₂ = 4y₁ y₂ and the moment of inertia about x and y axis being I_xx and I_yy respectively, then the stress at the corner D is
