Question $2$:

You are give a task to check the safety of a cantilever retaining wall $($Figure $2)$ to be constructed at the hill side of town plaza. The cross section of the cantilever retaining wall is shown in the figure below.

For the lateral earth pressure computation use Rankine's formulas. Take the unit weight of the concrete as $23\mathrm{.}5k\frac{N}{m}3$

Check $($Compute$)$ the factor of safety against sliding, overturning, and bearing capacity.

$0\mathrm{.}5$
