A square footing is shown in the figure below.

Init weight of soil $=$

Iroundwater table

'sat

Consider the following given information.

$=16\mathrm{.}5k\frac{N}{m^3}$

${}_{\text{s}\text{a}\text{t}}=18\mathrm{.}55k\frac{N}{m^3}$

$c^{\text{'}}=0$

${}^{\text{'}}=35$

$B=1\mathrm{.}8m$

$D_f=1\mathrm{.}38m$

$h=0\mathrm{.}69m$

Determine the gross allowable load, $Q_{\text{a}\text{l}\text{l}}($in $kN),$ that the footing can carry. Use Terzaghi's equation for general shear failure $)=(3.($Use any necessary data from this table.$)$

Your response differs from the correct answer by more than $10\%.$ Double check your calculations. $kN$
