A short rectangular post supports a compressive load of $P=1700lb$ as shown. A top view of the post showing the location where load $P$ is applied to the top of the post is also shown. The cross$-$sectional dimensions of the post are $b=7\mathrm{.}00in.$ and $d=10\mathrm{.}50in.$ The load $P$ is applied at offset distances of $y_P=3\mathrm{.}25in.$ and $z_P=1\mathrm{.}50in.$ from the centroid of the post. Determine the normal stresses at corners $A,B,C,$ and $D$ of the post.
