QUESTION THREE

The sketch below shows a gravity dam with a triangular cross$-$section. Given that ${}_c=2\mathrm{.}4K\frac{N}{m^2}$ and $=0\mathrm{.}8,$ Calculate the factors of safety against sliding and overturning $($FSs and FSO$)$ and the pressure at the toe and heel of the dam $(q_T$ and $($:$q_H\}.$ Neglect $(20$ Marks$)$ the uplift force.
