• Part A- Orientation of the planes of maximum and minimum normal stress A Learning Goal: To determine the in-plane principal stresses and maximum shear stress along with their orientations and the average normal stress for an element in a given state of plane stress. Determine the orientation of the planes of maximum and minimum normal stress, a and a. respectively. Use the value for 8a that is negative. Then use this value to determine the value of 8- Express your answers to four significant figures separated by a comma. > View Available Hint(s) The element of material below is subjected to the state of stress shown, where a = 114.0 MPa, 6= 56.00 MPa, and e= 22.00 MPa Eigure 1) 1, e Submit

Mohr’s circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 600 psi in size. (a) Determine the stresses σx, σy, and the magnitude of τxy and show them on a stress element. (b) Determine the principal stresses and the magnitude of the maximum in-plane shear stress acting at the point and show these stresses on an appropriate sketch (e.g., see Figure 12.15 or Figure 12.16).
