Design of Spars
In working on the Tern 2VS, I have come across a lot of information on the internet on how to size a spar for bending moment. Sadly, a lot of it seems to be generally wrong, and relies upon the underprediction of material properties to avoid disaster. I decided to evaluate how wrong the common method was, so I derived the correct equations. I put the writeup together here.
