10-12. The state of stress on a.small element is o, = 28 kPa, o = 14 kPa, %3D and the shear stress on the horizontal plane is +4 kPa. (a) Find the magnitude and directions of the major and minor principal stresses. (b) If the material is a loose sand, can you say whether the element is in a state of failure? If it isn't, how close is it? Why? State your assumptions clearly. (Assume o = 30° for the loose sand.) %3D
