All of the sources for this project either came from a handful of books, web sources, personal experience and knowledge from my engineering courses. An excellent book to read over to help understand the statics analysis would be Engineering Mechanics: Combined Statics & Dynamics by Russell C. Hibbeler (ISBN 9780138149291). To review how materials act under force, check out Mechanics of Materials, by the same author, (ISBN 0136022308).
The density, sheer, compression and tension strength values for the wood are pulled from http:www.wolframalpha.com.
