PROBLEMS$1.$ The floor system in Figure $8-22$ sits on a redwood sill on a concrete wall. Determine the number of$16-$foot$-$long pieces of redwood that are needed to complete the floor system$\mathrm{.}2.$ Determine the materials needed to complete the posts and girder supporting the floor joists in Figure $8-22.$ The posts are connected to footings using a Simpson PB$44$ post base and are connected$146$CHAPTER EIGHTto the girder using a Simpson BC$4$ post cap. The distance between the top of the footing and the bottom of the girder is $7$ feet. The posts are spaced $12$ feet apart$\mathrm{.}3.$ Determine the materials needed to construct the joists and joist headers for the floor system shown in Figure $8-22\mathrm{.}4.$ For the floor system shown in Figure $8-22,$ the joists are blocked over the girder, at the concreteDOUBLE JOSTwall at the overhang, and at the midpoint between the girder and the exterior wall on the joists over $8$ feet long. Determine the materials needed for the blocking$\mathrm{.}5.$ Determine the number of $4-$foot by $8-$foot sheets of$23/32-$inch T&G OSB sheathing that are needed to construct the floor system shown in Figure $8-22.$
