5. The vertical stress at a point is 28 kPa, while the horizontal stress is 14 kPa. shear stress on the horizontal plane is +4 kPa. The (a) Draw the Mohr's circle of stress and show the pole point (origin of planes). (b) Determine the major and minor principal stresses and show by means of a sketch the direction in which they act (use the pole point to determine the direction). (c) Determine the maximum shear stress and show by means of a sketch the direction of the two planes on which the maximum shear stress acts. 5.
