Problem $18$

A rectangular foundation $2m4m$ is constructed on a soil with property

$,$ Frictional angle $=38$

$,$ Cohession of soil $C=70\frac{KN}{m^2}$

Unit weight of the soil $=18\frac{KN}{m^3}$

Depth of the foundation $=2m$

$,$ load eccentricity $=0\mathrm{.}3m($for B direction$)$

Determine ultimate load bearing capacity using Meyerhof's effective area.
