Question:

An element in plane stress is subjected to stresses (x = - 50 MPa and Txy = 42 MPa (see figure). It is known that one of the principal stresses equals 33 MPa 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?
