The element of material below is subjected to the state of stress shown, where a = 120.0 MPa, b = 64.00 MPa, and c = 30.00 MPa (Figure below) a. Determine the orientation of the planes of maximum and minimum normal stress, θp1 and θp2, respectively. Use the value for θp2 that is negative. Then use this value to determine the value of θp1. b. Determine the in-plane principal stresses for the element (as oriented in Part A), and calculate σ1 and σ2 such that they correspond with θp1 and θp2. c. Determine the orientation, θs2, of the element subjected to maximum shear stress on its left and right sides. Use the value for θs2 that is positive. d. Determine the maximum in-plane shear stress and the average normal stress acting on an element oriented as determined in Part c.
