The element of material below is subjected to the state of stress shown, where a = 102.0 MPa, b= 70.00 MPa, and c= 10.00 MPa (Figure 1) {Figuret joi ¥ L., Part A - Orientation of the planes of maximum and minimum normal stress Determine the orientation of the planes of maximum and minimum normal stress, @p1 and Opa, respectively. Use the value for Oyo that is negative Then use this value to determine the value of Ap, Express your answers to four significant figures separated by a comma. + Hints Mm Goer oea? Opry Op = . Part B - In-plane principal stresses Determine the in-plane principal stresses for the element (as oriented in Part A), and calculate 7% and » such that they correspond with ®p1 and Opp. Express your answers to four significant figures separated by a comma. > Hints GIGG--os: 01, 09 = MPa, MPa https://skippy.buzz/view
