An element in plane stress is subjected to stresses (x = 5700 psi and Txy = - 2300 psi (see figure). It is known that one of the principal stresses equals 6700 psi in tension.
(a) Determine the stress (y.
(b) Determine the other principal stress and the orientation of the principal planes, then show the principal stresses on a sketch of a properly oriented element.
