Problem 3 The state of stress on an element is shown below. Using Mohr's Circle determine a. The principal stresses and maximum in-plane shear stress b. The average normal stress c. The orientation of the principal planes from the point shown. d. The absolute maximum shear stress (draw a separate set of Mohr's Circles for this part) e. The state of stress on a point rotated 15 degrees clockwise from the one shown below. f. Verify the transformation using the transformation equations. 6 MPa 8 MPa 5 MPa
