$($Q$)$

Design the vertical stem of a $T-$shaped retaining Wall for a height of $3m$ above the ground leval. The Tol of the earth retained in surchagged at $10$ with the horigontal. The angle of repose of the earth ${29}^{.}$and, its density is $17k\frac{N}{m^3}$ The safe braving

Cepaity of the Soll is $100k\frac{N}{m^2}$ and $($afficint of friction b$/$v cancests and soll is $0\mathrm{.}55.$
