Do the problems below:

J$\mathrm{.}1$ Use table $5\mathrm{.}10$ to select the smallest possible cross$-$section for floor joist with LL $=40$psf and DL $=20$psf$,$ max LL deflection $=$ L$/360$

spacing $24"$o$.$c$,$ span$=12\text{'}$

spacing $16"$o$.$c$.,$ span $=14\text{'}$

spacing $12"$ o$.$c$.,$ span$=18\text{'}$

J$\mathrm{.}2$ Use table $5\mathrm{.}11$ to select the smallest possible cross$-$section for rafters with LL$=20$psf and DL $=10$psf$,$ max LL deflection $=$ L$/240$

spacing $24"$o$.$c$,$ span$=20\text{'}$

spacing $16"$o$.$c$.,$ span $=16\text{'}$

spacing $12"$ o$.$c$.,$ span$=14\text{'}$

J$\mathrm{.}3$ Using ASD method, find the allowable axial compression load for the following wood columns:

$4$x$4,$ unbraced length $15\text{'}$ with HemFir No$.1$ grade

$6$x$6,$ unbraced length $22\text{'}$ with Doug$-$fir Larch, Dense No$.1$ grade

J$\mathrm{.}4$ Use table $6\mathrm{.}1$ to find the smallest SQUARE cross$-$section needed for the following conditions:

Note: since you must use table $6\mathrm{.}1,$ you must be assuming Doug$-$Fir Larch, No$.1$ grade

$12\text{'}$ unbraced length, P$=24$k

$19\text{'}$ unbraced length, P $=12$k

J$\mathrm{.}5$ Combined Axial and Bending loads: A WLF exterior wall is made with $2$x$6$ studs and are each exactly $12\text{'}$ tall. Use Doug Fir$-$Larch No $1$ grade. The wind load on the wall is $24$psf on the wall surface, studs are $16"$ o$.$c$.,$ and the gravity load on the wall is $500$ #$/$ft of wall length. The exterior sheathing is nailed at $10"$o$.$c at each stud. Investigate the studs for combined action of compression plus bending using the ASD method.
