The state of stress at a point in a structural member is given to be: Ox=-500 psi, oy = 1400 psi, and Txy = 

The state of stress at a point in a structural member is given to be: Ox=-500 psi, oy = 1400 psi, and Txy = +500 psi (plane stress sign convention). Determine: (1) The principal stresses and the maximum in-plane shear stress at the point. (2) The orientation of the principal planes. (3) The normal and shear stress on a plane located 80 clockwise from the horizontal plane.
