Shear Stress 4. Please provide proper discussion and illustration. Clear and complete solution please thank you.  Design studies for a planned building indicate that the foundation loading will cause the principal stress in the soil at one point below the building area to increase to 195 kPa and 70 kPa (major and minor principal stress values, respectively). If the soil is a dry sand having an angle of internal friction equal to 340, determine if the indicated stresses would cause shear failure to occur.
