A long footing, 1 m wide, has its base inclined 10° from the horizontal. The footing bears on the surface of a soil for which drained shear tests show a cohesion of 24 kPa and an angle of internal friction of 25°. The soil rigidity index value is 50. What load acting normal to the foundation base can be imposed if a factor of safety of 3 is used with the extended general bearing capacity equation?
