Ive got a question regarding floor joists.
Say you have a 2×8 beam, is it fair to say that if you placed two 2×4 side by side that it would support around the same amount of weight?
And anyone know how much weight a 5x5x20 beam could support over 19.2′ (5×5 beam supported by a 5×5 beam on both sides) being used as a FLOOR joist, (having plywood over the top like a regular floor system) 16″ OC
