A state of stress that occurs at a point on the free surface of a solid body is: σx = 60 MPa; σy =0 MPa; τxy =30 MPa a. Evaluate the two principal normal stresses and the one principal shear stress that can be found by coordinate system rotations in the x‐y plane, and show the coordinate system rotations to these principal stresses with sketches of the elements for both principal normal stresses and principal shear stresses, correctly oriented relative to x & y axes. b. Determine the maximum normal stress and the maximum shear stress at this point. Indicate which planes upon which these maxima are acting. That is, be sure the resulting maxima are labeled with the correct and appropriate subscripts.
