Consider a continuous $($strip$)$ footing with a depth of $1\mathrm{.}5$ m and a width of $5$ m$.$ The soil has a moist unit

weight of $19\mathrm{.}7$ kN$/$m$^3,$ a drained cohesion of $19$ kPa, and a drained friction angle of $31$ degrees. If designing to a

factor of safety of $4,$ find the gross allowable load per unit area $($qall$,$ assuming shear failure and using Terzaghi$$s

bearing capacity factors$).$
