How long mail takes is going to depend on many factors along the way. Many factors, indeed, though with regard to how long does priority mail take, the answer is, not long. In fact, the United States Postal Service says your package or envelope will arrive within two days.
Both the 2009 IRC and the DCA6-09 allow #2 southern pine 2x10s to span 13 feet 1 inch at 24 inches on-center at a design load of 50 psf. That means these joists can span the 12-foot depth of the deck, and the beam can be located at the perimeter. Nine joists will be needed for the 16-foot width.
Not really. All joists will be the same whether you are working on a 1st or second floor, so your floor does not have a bunch of different levels. Usually we use 2 x 12 â¦ lumber, doubling joists which have walls above them or decreasing the spacing if you are at the limits of the span. example you have a 22' span in a garage with living area above it, you would use 2 x 12 with 12 on center spacing.
