A rectangular foundation $(2m4m$ in plan$)$ is built on sandy soil $($effective friction angle $=35,$ dry unit weight $=16\mathrm{.}5\frac{kN}{m^3},$ and saturated unit weight $=17\mathrm{.}5\frac{kN}{m^3}).$ Determine the ultimate bearing capacity of the foundation if the load is inclined at $10$ with respect to the vertical line. Assume that the depth of the foundation is $1\mathrm{.}0$ m $,$ the water table is at the ground surface, and general shear failure occurs in the soil.
