Solve the preceding problem for an element in plane stress subjected to stresses (x - 100 MPa, (y = 80 MPa, and Txy = 28 MPa, as shown in the figure.
Determine the stresses acting on an element oriented at an angle ( = 30° from the x axis, where the angle ( is positive when counterclockwise. Show these stresses on a sketch of an element oriented at the angle (?
