A masonry dan has given cross section shown. The intensity of the hydrostatic uplift varies uniformly from $80\%$ of the full hydrostatic at he heel to $20\%$ of the full hydrostatic at the toe. specific gravity of concrete is $2\mathrm{.}4,$ determine the following:

A$.$ Total verticel reaction at the bottom of the dam. $398\mathrm{.}286kN$

A$.$ Factor of sa ety against sliding if the coefficient of friction at the base is $070,0\mathrm{.}702$

C$.$ Factor of saffty against overturning. $1\mathrm{.}253$

D$.$ Minimum anf maximum soil pressure, $0$kPa and $183\mathrm{.}627$kPa
