A question on wood strengh:
Well I came across this the other day and have a question about it.
I know this DIY stand for a 4 foot standard tank uses 2X4s. I also know that two 1X4s glued together lenght wise are stronger than one 2X4, by about 125~150%.
However, I saw boards the other day in 8 foot lenghts, the wood is 1 3/4" by 3 3/4" (so basically 1/4" biggest than a 2X4) and made up on many pieces of wood glued together and joined with the basically dove tail joints in certain sections.
My question is, is this the same strength as a 2X4, stronger than a 2X4 or weaker than a 2X4? I realize a 2X4 is actually 1.5" By 3.5" so this is 1/4" bigger all around, but approx. the same. Would I be better of using this or 2X4s? In weight and size a 2X4 looks so small.
