A smooth backed vertical wall is $5\mathrm{.}3m$ high and retains a soil with a bulk

unit weight of $=23\mathrm{.}9k\frac{N}{m^3}$ and $=37.$ The top of the soil is level

with the top of the wall and is horizontal $.$ If the soil surface carries a

uniformly distributed load of $q=19k\frac{N}{m^2},$ as shown in the figure below.
