Unformatted text preview: direction and 140 MPa compression in the vertical direction (see figure). Also, shear stresses of magnitude 60 MPa act in the directions shown. Determine the stresses acting on an element oriented at a counterclockwise angle of 48 from the horizontal. Show these stresses on a sketch of an element oriented at this angle.
