Determine the normal and shear stresses at point D that act perpendicular and parallel, respectively, to the grains. The grains at this point make an angle of 30 with the horizontal as shown in the figure below. Point D is located just to the left of the force P = 14 kPa. (Figure 1) Part A Determine the normal stress at point D that acts perpendicular to the grains. Express your answer using three significant figures and include the appropriate units.
