The state of stress at a point is as shown below. (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. (d) Determine the normal and shear stress on a horizontal plane. 55 8 kPa 2 kPa 4 kPa The state of stress at a point is as shown below.
