A $4$x$8,$ No$.1,$ Douglas Fir$-$Larch joist $($strong axis

bending$)$ is supported by a $66,$ No$.1,$ Ponderosa

Pine column. The joist rests on the column such that

the bearing length of the joist covers the entire width

of the vertical column and the joist is centered on the

vertical column in the other direction $($transverse

direction of the joist$).$ The vertical force transferred

from one member to the other at the connection is

$10,000lbs,$ with a load duration factor of $1\mathrm{.}25$ and an

equilibrium moisture content of $20\%.$

What is the actual bearing stress on each member?

$395$ psi

$520$ psi

$420$ psi

$210$ psi
