A strip footing foundation 1 m wide is constructed in the slope of a hill whose surface inclination is 20°. The soil in the hill is a dense sand, with a unit weight of 19 kN/m³
and an angle of internal friction of 40°. Assume that the D/B ratio is about 1. Applying a factor of safety of 3, determine the wall loading the foundation can carry, per meter of footing length.
