At a point in a stressed material, the stress combination acting on a plane is 60 kPa compression and 20 kPa shear, while on an orthogonal plane, the stress combination is 40 kPa tension and 20 kPa shear. Use the Mohr’s circle for this stress analysis.

(a) Determine the values for the major and minor principal stresses.

(b) Determine the value of the maximum shear stress and the value of the normal stress on the plane of maximum shear.
