11121Re: [MedievalSawdust] Wood load strength
- Mar 1, 2009USDA publishes a book of engineering data for wood structures. That would be your best bet. It will give you shear strengths and other values for most commonly used woods. You'll have to do the engineering calcs yourself - resolving the stress vectors, calculating bending moments, shear stress, etc, before you can use any of the values in the book. Anyone who struggled through Strength of Materials in college will tell you that's not a trivial exercise!
But you can't go too far off by using the same wood and the same dimensions as the original chairs. Dantescas are pretty strong if you cut that crossing-joint carefully and use good wood. Avoid red oak or other coarse-grained, easily-split wood. If you're really concerned for strength, find some elm.
Does anyone have a good site or book for figuring the weight load a piece of wood can take? I am making a dantesca chair and wonder how much of a limit it can take and if there is any way to strengthen it.
