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

Problem 3 Find the solutions to the general cubic a x^3 +b x^2+c x +d=0 and the solutions to the general quartic a x^4+b x^3+c x^2+d x+e=0. Remember to put a space between your letters. The solutions to the general quartic goes on for two pages it is a good idea to maximize your page to see it. It is a theorem in modern abstract algebra that there is no solution to the general quintic in terms of radicals.
