text: Of course, it could be that the face is perpendicular to the base, but I think the picture should be redrawn.
text: The resultant forces of the hydrostatic pressure on the lower face AB, and upper face, CD, of the parallelepiped are perpendicular to the potential slide plane AB and, therefore, they do not contribute to the resultant force in parallel direction to the shear plane.
