Can you not extrapolate the answer from the data you already have?

True, my initial posts were overly brief, but I was trying to avoid writing large essays to answer short questions. Ended up having to do a lot more work than if I had just started out correctly, so perhaps then wasn't the best time to get lazy.

Well, even though the manufacturers will express their data as a straight function of Nm/Degrees, it's not really that simple here. As the frame flexes members that had no or insignificant forces acting upon them initially begin to take force loads of their own and this effects the overall forces in a nonlinear manner. So it's not really proportionate to the forces. I messed around with the software we have for a few minutes, but I couldn't find an easy way of finding out the forces required for 5 inches, since that's kind of backwards to what he have been using it for. I'm not sure that the frame could support a flex of 5 inches, or if members would start to buckle.

If you really wanted to you could look up the manufacturers numbers and use the Nm/Degree equation with a little trig for the length of flex. It wouldn't tell you real world forces such as g's sustained, but you'd at least have a very rough idea of what forces would have to act on the frame. If it wasn't so close to finals week I'd spend more time on this, but I'm beginning to think that going for a second major as an undergrad while I'm doing grad work may have been a mistake. The only reason I've been getting on this site is that I need a chance to uncross my eyes every once in a while.
