2. For the bi-axial stress states listed below, draw the stress element. Calculate the principal stresses, and determine the angle from the x axis to the largest principal stress (01). Draw the new stress element at the principal orientation. Don't forget to label all details. = -8MPa, = 7MPa, Tay=-6MPa 2. For the bi-axial stress states listed below, draw the stress element.
