5) For the plane stress states listed below, draw a Mohr's circle diagram properly labeled (10 points), find

the principal stresses (10 points) and shear stresses (5 points), and determine the angle of the 1st principal

plane from x axis (5 points). Draw stress elements of the principal plane including its orientation (10

points) [40 points]
