A rectangular shallow foundation $6$ mx $4$ m is subjected to an eccentric load

with eccentricities $e_B=0\mathrm{.}45m$ and $e_L=1\mathrm{.}2m.$ If the depth of foundation is $2$ m $,$

determine the allowable load that the foundation can carry. Use factor of safety

of $3,$ unit weight of the soil is $17k\frac{N}{m^3},=35$ and $c=0.$
