Q2- A strip footing $(1.5+0.1\mathrm{N})\mathrm{m}$ wide placed at a depth of $0.8\mathrm{m}$ below the ground surface and subjected a uniform pressure of $(150+3\mathrm{N})\mathrm{KPa}$. Determine the vertical stress under the foundation at a depth of $(1.8+0.1\mathrm{N})$ $\mathrm{m}$ and deviates a distance of $1.5\mathrm{m}$ from the vertical line of the strip edge. Compare this result of the stress with the stress if the point is considered to be $1.0\mathrm{m}$ deeper.
