A $10-$foot long, $3$x$,$ No$.1$ Hem$-$Fir timber

member is to be designed to carry an axial

tension load of $20\mathrm{.}8$ kips. The member is

fastened at each end with a single row of $7/8"$

diameter bolts through the short dimension, with

a $\frac{1}{8}"$ hole clearance. The member is

manufactured and used at $10\%$ moisture

content, and is critically loaded with wind load.

Assuming that the connection is adequate,
