$1.$ A Douglas fir stud $1\mathrm{.}5"x{3\mathrm{.}5}^{\text{'}\text{'}}8ft$ long is subjected to an axial compression load of $1000lbs.$ What is the stress in the stud? What is its change in length?

$2.$ A Douglas fir floor joist, ${1\mathrm{.}5}^{\text{'}\text{'}}{11\mathrm{.}5}^{\text{'}\text{'}}12ft$ long is subjected to a uniform load of $100l\frac{b}{f}t.$ What is the maximum deflection? What is the maximum stress?

$3.$ Wood blocking is to be used to support the keel of a $600$ ton vessel in dry dock. What direction should the blocks be oriented? What type of wood would you use? Why? If the keel is $6$ inches wide, how many feet of blocking are required?
