$4\mathrm{.}13$ The shallow foundation shown in Figure $4\mathrm{.}24$ measures $1\mathrm{.}5m2\mathrm{.}25m$ and is sub$-$

jected to a centric load and a moment. If $e_B=0\mathrm{.}12m,e_L=0\mathrm{.}36m,$ and the depth of

the foundation is $0\mathrm{.}8$ m $,$ determine the allowable load the foundation can carry. Use a

factor of safety of $4.$ For the soil, we are told that unit weight $=17k\frac{N}{m^3},$ friction

angle ${}^{\text{'}}=35,$ and cohesion $c^{\text{'}}=0.$ de
