$14.$ If the joists in Question $13$ must span a distance of $5$ ft$,$ what size of joist would be required to support the calculated loads assuming a two$-$span continuous situation?

$$

$15.$ Based on the loads in Question $13$ and assuming that the joists were supported by beams that were to span $10$ ft$,$ what total load would result on the shore posts supporting the beams?

$$

$16.$ If the shore posts in Question $15$ had an unsupported height of $10$ ft$,$ what size of wood post would be required, assuming an S$4$S section with an allowable compressive stress parallel to the grain of $1,100$ psi is to be used?
