A brick wall with a width of $B=48ft$ is placed in front of the ENG$2$ building. The load per

unit area $q=1,650l\frac{b}{f}{t}^2.$ A water meter $($at location $A)$ is installed $21ft$ below the ground

surface, and $x=28\mathrm{.}8ft$ away from the center of the center line of the wall.

Determine the induced vertical stress applied on the water meter $(5pts.$

If the water meter is buried a$)$ deeper and b$)$ closer to the centerline of the brick

wall, what will the induced vertical stress change? $(10$ pts$)$
