Find the allowable compressive load for a $68$ Douglas$-$Fir$-$Larch No$\mathrm{.}1,$ S$4$S solid wood

corner column as shown under normal load duration $($ten years "normal load"$).$ Column is

assumed fixed at the bottom, pined top and all other connections as pin connection.

Actual dimension for $68=5\mathrm{.}57\mathrm{.}5,$ Area $=41\mathrm{.}25in2,E=1700$ksi and $Fc=1500$
