A soil specimen (100mm x 100mm x 100mm) is subjected to the forces shown in Figure. Determine the magnitude of the principal stresses, the orientation of the principal stress plane to the horizontal, the maximum shear stress, and the normal and shear stresses on a plane inclined at 20 degrees clockwise to the horizontal.
