Problem 2: A 3 ft x 5 ft (B x L) rectangular footing is shown in
following figure. Using generalized bearing equation (with shape,
depth and inclination factors), determine the allowable (safe) load
that the foundation carry. Given: gamma = 115 lb/ft3 , c’= 1100
lb/ft2 , phi’ = 35°, Df =3.5 ft, Ground water table is located at 5
ft below ground level. Assume factor of safety = 3. Assume gammasat
= 127.4 lb/ft
