Hi,
I'm hoping to better understand the physics involved in building a platform for storage.
I have an exterior wall with a 2x6 header nailed horizontally into it.
10' in from that wall, I have 2x6's vertically from concrete floor up.
On the top of the header and vertical 2x6's is a 2x4 rectangular frame (10' x 20').
I believe that the interior wall of 2x6 has a far (far) greater capacity to hold weight because compression strength of 2x6 is pretty darn high (that's not a technical term).
The header, on the other hard, is nailed. This means (I believe) that the holding strength is a function of the sheer strentgth of the nails and the friction between the header and the wall.
My question is: Does the placement of the load on the 3/4" plywood sitting on the 2x4 frame change the max weight capacity of that load?
Put another way (because I don't speak engineering or physics well), if I put the entire load on the inside edge of the platform (directly above the 2x6 supports) do I get a greater load capacity than putting the load directly above the header nailed to the wall?
Here's some pics to clarify.
Thank you!
Joseph
