Question $6$

A strip footing $2\mathrm{.}5$ m wide carries a uniform pressure of $138k\frac{N}{m^2}$ on the surface of a sand deposit. The water table is at the surface, and saturated unit weight of sand of $21\mathrm{.}9k\frac{N}{m^3}.$

Determine the effective vertical stresses $($ KP $)$ at a point $2\mathrm{.}2$ m below the point $3\mathrm{.}2$ m from the centre of the footing to the RIGHT after the application of the pressure. $(2$d$.$p$).$ Use unit weight

of water $9\mathrm{.}8k\frac{N}{m^3}$
