$3-.$ A soft clay stratum is found to have liquid and plastic limits of $110$ and $35,$ respectively. A series of vane shear tests with a vane in a dimension of $60mm$ in diameter and $120mm$ long are performed at different

depths. The measured torques at depths are provided below:

$\backslash$table$[[$Depth $($m$),4\mathrm{.}0,5\mathrm{.}0,6\mathrm{.}0,7\mathrm{.}0,9\mathrm{.}0],[$Tf $($N$-$m$),8\mathrm{.}3,9\mathrm{.}4,10\mathrm{.}5,12\mathrm{.}3,15\mathrm{.}2]]$

Calculate the soil uncorrected and corrected undrained

shear strengths at each depth and then develop a profile of corrected undrained shear strength versus depth.
