$10\mathrm{.}18$ Figure P$10\mathrm{.}18$ shows a foundation in a medium dense sand deposit with the soil properties

shown. The foundation dimensions are $6\mathrm{.}4ft11\mathrm{.}5ft,$ and the depth of the foundation,

$d=2\mathrm{.}5ft.$ The depth from the foundation base to the rigid stratum, $H=32ft.$ Determine

the elastic settlement under a corner of the foundation for an applied stress, $q=3000psf.$
