A continuous footing is $1\mathrm{.}8$m wide and is founded at a depth of

$0\mathrm{.}75$ m in a clay soil of unit weight $20$ kN$/$m$3$ with $=0\backslash$deg and cu

$=30$ kN$/$m$2$

$.$ The foundation is to carry a vertical line load

which will act a distance of $0\mathrm{.}5$ m from the center. The weight

of the footing will exert a uniform pressure if $12$ kN$/$m$2$ on to

the soil. Determine the value of safe bearing capacity for the

footing, taking FS $=3\mathrm{.}0,$ and determine a safe value for the line

load.
