Q$4.$ For a rectangular foundation, the following are given:

$B=1\mathrm{.}5m($ width $),L=2\mathrm{.}5m(length),D_f=0\mathrm{.}5m(depth),=18\mathrm{.}8k\frac{N}{m^3},{}^{\text{'}}=32,c^3=$

$10$kPa

Use Terzaghi and Vesic Equations and a factor of safety of $2\mathrm{.}5$ to determine the allowable

bearing capacity and the maximum column load to cause bearing capacity failure. Assume

that general shear failure occurs in soil.
