Question: 3 - 3 . A 1 0 - foot by 1 0 - foot square footing to carry a total load of 4 2 5

3-3. A 10-foot by 10-foot square footing to carry a total load of 425 tons is to be installed 8 feet below ground surface on a sand stratum. Standard penetration tests were conducted on the site. Test results were corrected for overburden pressures, and the corrected N-values are listed as follows:
\table[[Depth (fi),Corrected N-Values],[2.0,14],[4.0,26],[6.0,38],[8.0,28],[10.0,19],[12.0,21],[14.0,25],[16.0,28],[18.0,31],[20.0,27],[22.0,28],[24.0,34],[26.0,29]]
No groundwater wals encountered during the subsurface exploration. Estimate the maximum expected settlement of the footing. Use Bazaraa's method.
