Hensley Arrow: How does it REALLY work?
There have been several discussions on this hitch that have become somewhat 'controversial'. I am NOT trying to stir this controversy/bashing back up. Instead, I'd like to see a good, intelligent di...

Ron, nobody is discounting or disputing the value of the analyses you put forth on this subject. You've been able to quantify the physics and geometry of the HA equation very clearly, if not a bit complicated for your average marketing guy :B
I'll go out on a limb and say that both Will and I agree with everything you have said to this point. However, what we are saying is that in addition to all that, the tension that exists between TV and TT as the TT is being towed adds additional resistance to ANY movement of the 4-bar linkage, particularly inputs from the TT.
Can you formulate a proof that shows that these forces do not affect the behavior of the HA? I think that would effectively let the air out of our tires.
I agree with Don 100% here. We agree with everything you've said, Ron, and all of your analysis. We just think (based on what we've personally experienced, and seeing how the Hensley pivots) that there is a bit more to it that is being overlooked, thats all.
That 'more to it' is that when the Hensley is under tension/pulling, it really appears that this effectively locks the trailer, and prohibits it from inducing any pivoting. When that 'pulling' affect goes away, then all your analysis/diagrams indicating how the Hensley allows pivoting, are right on.
As far as Ron proving these affects do not change behavior, that'd be just about as difficult, as us PROVING these affects DO change behavior. LOL! Either way, one of us is going to have to build this 'model' we've talked about, and see what happens. :)
