You can also test a scale model of a spar and obtain good results. Stan Hall discussed the methodology for this in an early Sport Aviation article, two actually.

And as far as a test setup and apparatus, check out http://www.flysquirrel.net/wing/spartest.html and see if you can duplicate the high-tech test setup detailed there... PS; I'm an engineer and I find no fault with this type of "first cut" analysis to see if you're even in the ballpark. This type of test can be prepared one weekend and run the next (after cure). You numerical types may take exception, but I don't. If it fails in this type of "backyard" scenario, you've got no business flying it at Reno!
