A pad footing of dimensions 1.2 m by 2.5 m applies a surface pressure of 425 kPa. The pad footing is underlain by a 1 m thick layer of gravel soil, then a 4 m thick layer of clay soil. Using the "2:1 load distribution of a rectangular load" method, calculate the applied pressure beneath the footing at the top of the clay layer, and 1.5 m below the top of the clay layer.
