What does the Red Triangle with an R mean?

on a building, it apparently tells firement the building has a (R)egular roof as opposed to a truss roof. Truss roofs tend to colapse in fires, so firemen do not get on top of it.


What is the strongest geometric shape?

The triangle is the strongest geometric shape, as it holds its shape and has a base which is very strong. The triangle is common in all sorts of building supports and trusses. If all three sides of a triangle are made of rigid material, the angles are fixed and cannot get larger or smaller without breaking at the joints, unlike a rectangle, for example, which can turn into a parallelogram and even collapse totally. If you take a rectangle and place one diagonal piece from corner to corner, you can make that strong and stable, too, but doing that makes two triangles.


What are structures that rely on triangulation for their strength?

Structures that rely on triangulation for their strength include bridges, trusses, and certain types of roofs. Triangular shapes distribute weight evenly and provide stability, making them ideal for supporting heavy loads. Common examples are the truss bridges, which use triangular units to efficiently transfer forces, and geodesic domes, which utilize triangular frameworks for strength and lightness. This design principle helps prevent deformation and enhances overall structural integrity.


Can a 4X8 beam support a floor with a span of 13 feet?

Technically Yes, but you'll need to check with your building inspector because there are codes regarding structure that vary from place to place, and the inspector isn't going to pass something based on my say so.The old rule of thumb was 1 inch for 1 foot, so a 12 foot span would require a 2 x 12.A 4 x 8 isn't equal to a 2 X 16, or even 2 2 X 8's, but it should do if the load isn't too great.I'm guessing you want to go with 8" stock because you've got some headroom issues. You'd be better off structurally with an LVL (Laminated Veneer Lumber) or OSB (Oriented strand Beam) or a truss, but these are kind of pricey.If you get in trouble see if they'll let you go with them on 12" centers.
