Work problem $1\mathrm{.}4$ again, only use a precise calculation for the wall assembly based on the following: $6",16$ ga steel studs spaced $24"$ on center. The $16$ ga studs weigh $1\mathrm{.}5$ lb$/$ft$.$ The studs are supported by a runner track top and bottom $($these are the equivalent of bottom and top plates on a wood wall$).$ There is a single track on top and on bottom. The tracks are $6",16$ ga also, and they weigh $1\mathrm{.}75$ lb$/$ft$.$ Two layers of $5/8"$ GWB each side $(4$ layers total$).$ The GWB weights $4\mathrm{.}16$ psf$/$in$.$
