A single vertical force $P$ is applied to a short steel post as shown. Gages located at $A,B,$ and $C$ indicate the following strains:

${}_A=-600,{}_B=-1000,{}_C=-200$

Know that $E=29{10}^6$ psi. At the hidden edge of the post, $x=-2\mathrm{.}5$ in$.$ and $z=-1\mathrm{.}5in.$

NOTE: This is a multi$-$part question. Once an answer is submitted, you will be unable to return to this part.

Determine the magnitude of $P.$

The magnitude of $P$ is $$ kips.
