Q$\mathrm{.}2.$ An excavation $8$ m deep in a cohesive soil $(c=50k\frac{N}{m^2}$;$=15k\frac{N}{m^3})$ is braced by struts at vertical spacings $2$ m starting $1\mathrm{.}0$ m from the top. The rows of the struts are horizontally spaced at $5m\frac{c}{c}.$ Evaluate the compression in the struts for design purposes.
