A Douglas fir stud ${1\mathrm{.}5}^{\text{'}\text{'}}{3\mathrm{.}5}^{\text{'}\text{'}}8ft$ long is subjected to

an axial compression load of $1000$ lbs$.$ What is the

stress in the stud? What is its change in length?

A Douglas fir floor joist, $1\mathrm{.}5"11\mathrm{.}5"12ft$ long is

subjected to a uniform load of $100l\frac{b}{f}t.$ What is the

maximum deflection? What is the maximum stress?

Wood blocking is to be used to support the keel of a
