A material element experiences 50 MPa compression in the x-direction, 10 MPa tension in the y-direction, and a negative 40 MPa shear stress.
(a) Construct Mohr's circle.
(b) Determine the stresses acting on an element inclined at 45 degrees. Show this element properly oriented with the associated stresses.
(c) Determine the principal stresses and the associated principal plane. Show this element properly oriented with the associated stresses.
(d) Determine the maximum shear stress. Show this element properly oriented with the associated stresses.
