Question $6$

Please utilize the United Soils Classification System table Figure $2\mathrm{.}3$ G and the Allowable Foundation and Lateral Pressure table Figure $2\mathrm{.}6$ in the textbook.

Using the allowable foundation pressure in $"$psf$",$ or pounds per square foot, for a certain class of soils material, you have determined a $\text{'}($ft$)$ square column footing is needed in order to support a load of $50,000$ pounds on a compacted, well$-$graded sand or well$-$graded sand with gravel, having little or no fines.

$1-$Locate the Group symbol in Figure $2\mathrm{.}3$

$2-$Find the class of material in Figure $2\mathrm{.}6$

$3-$Identify the Allowable Foundation Pressure $($AFP$)$ in $"$psf$."$

$4-$Divide $\backslash (50,000\backslash$mathrm$\{$lbs$\}\backslash ).$ by the AFP.

$5-$Using a Calculator, find the square root of the number you determined in $(4.)$ above.
