A $5$ ft wide continuous footing is founded at a

depth of $5$ ft$.$ The soil above the bottom of the

footing is granular with a friction angle of $30$ deg,

cohesion of zero, and a unit weight of $115$ pcf$.$ The

water table is $1$ ft below the bottom of the footing.

The soil below the footing has a friction angle of

zero, a cohesion of $2000$ psf$,$ and a unit weight of

$120$ pcf$.$ Solve for the nominal bearing capacity

using Terzaghi bearing capacity factors
