determine the largest compressive load $($P allowable$)$ that can be supported by a $4$x$4$ shore which is $12$ feet tall. a duration factor of $1\mathrm{.}25$ No$.2$ and exists under normal moisture, temperature, and other conditions $($all other modifiers $=1\mathrm{.}0$ but consider the stability factor$).$ Assume the column to have an effective length factor of $1\mathrm{.}0$ and ASD principles.
