Solving this by trial and error, we water sable is $1m$ below G$.$L$.$ The allowable soil pressure for sand very great depth is $50\frac{t}{m^2}.$ Saturated and dry are $2\frac{t}{m^3}$ and $1\mathrm{.}6\frac{t}{m^3}.$

For $=36$;$N_c=50$;$N_q=42$ and $N_{}$ what will be the allowable footing is eccentric with $e_x=e_y=0\mathrm{.}25$ m$,$ why.
