Problem 9.19 3 of 6 Determine the equivalent state of stress on an element at the same point which represents the principal stress, and the maximum in-plane shear stress and the associated average normal stress. Also, for each case, determine the corresponding orientation of the element with respect to the element shown in the figure below. Suppose that T= 28 MPa. (Figure 1) Part A Determine the orientation of principal planes of stress. Express your answers using three significant figures separated by a comma.
