A square plate with side dimension of 2 in, is subjected to compressive stress σ_x and tensile stress σ_y. The stresses on element A oriented at angle u = 458 are σ_x = - 75 psi, σ_y = - 75 psi, and π_xy = - 75 psi. Find the state of stress on the element if it is rotated clockwise to align the x₁ axis with the horizontal x-axis.
