A $3-m3-m$ square column footing is $1\mathrm{.}8m$ deep and is loaded with a $330kN$ vertical

load $($including weight and soil load$)$ and an $80kN$ horizontal load. Find the factor of

safety against sliding, overturning, and bearing capacity. Assume a coefficient of

friction of $0\mathrm{.}4.$ The soil properties:

$c=2k\frac{N}{m^2}$

$=35\mathrm{.}1$

$=17\mathrm{.}8k\frac{N}{m^3}$
