Q$\mathrm{.}23\backslash$gamma $=20\mathrm{.}5$k$($N$)/($m$^(3)).$ Undrained shear box tests give shear strengths of $35,47$ and $59$ k$($N$)/($m$^(2))$ for normal stresses of $70,140$ and $210$k$($N$)/($m$^(2)),$ respectively. Find the apparent cohesion c and angle of shearing resistance $\backslash$phi $,$ and then calculate the gross ultimate load per meter run of foundation immediately after construction. Consider bearing capacity failure only. Use Terzaghi bearing capacity equation.
