Problem $5\mathrm{.}41$

The bulk head $AD$ is subjected to both wates and soil$-$backfill pressures. The bulk head has a mass of $750$ kg $.$ Suppose that $w_{\text{w}\text{a}\text{t}\text{e}\text{r}}=113$ kN$/$m and ${}_{\text{s}\text{o}\text{i}\text{l}}=340$ kN$/$m$.$

a$)$ Assuming $AD$ is "pinned" to the ground at $A,$ determine $x$ and $y$ components of reaction at A necessary for equilibrium.

b$)$ Determine the required tension in the ground anchor BC necessary for equilibrium.
