Question $1$:

For the slope shown in Figure $01,$ find the factor of safety of the slope using the ordinary method

of slice. Also determine the critical height of the slope assuming undrained condition $($use the

available cohesion value where necessary$).$ The water table is located at the ground surface and

parallel to it$.$ Explain the safety of the slope and suggest at least one action that can be considered

to make the slope stable $($if unstable$).$

Figure $01$

Use the following table to find the missing values $($where $x$ and $h$ are given in meters, and $$

is measured in degrees$)$
