7. A continuous wall footing with a width of 3 feet is proposed for a tall warehouse. The wall loads are expected to be approximately 6 kips per lineal foot. A soft clay layer was encountered below the base of the footing as shown in the figure. Estimate the increase in vertical stress (ps) below the center of the continuous footing at the midpoint of the soft clay layer.(10 pts.) Hint: What units are you given in the problem and what units is the answer supposed to have? F1
