A rectangular footing has a size of $2\mathrm{.}0m4m$ has to transmit the load of a column at a depth of $1\mathrm{.}5m.$ Calculate the safe load which the footing can carry at a factor of safety of $3$ against shear failure. Use IS code method. The soil has following properties: Porosity, $n=45\%$; Specific Gravity, $G=2\mathrm{.}65$; water content, $w=18\%$; Cohesion, $c=12k\frac{N}{m^2}$; Angle of shearing resistance $=32$; For $=32,Nc=36$;$Nq=23$ and $Nr=30.$ Compare it with Terzaghi's theory also.

Please as soon as possible and put the solution on a sheet of paper with step by step solutions and shiw any unit conversion
