A $30m$ height slope is to be built as shown below. The homogeneous with c$\text{'}=30k\frac{N}{m^2}$ and ${}^{\text{'}}=32.$ The unit weight of soil is $18k\frac{N}{m^3}.$ Using the ordinary method of slices, compute the factor of safety along the potential failure surface. In your calculations, you should also consider the seven$-$meter depth tension crack. $($FS check $=2\mathrm{.}00$ and $($:${}_w=10k\frac{N}{m^3}\},$
