There seem to be a lot of people who have been so confused by Hensley's test model that they really believe that there is some kind of magic in the 4-bar linkage that allows a bend to be initiated from only one end (the TV end). It just isn't possible for a 4-bar linkage to freely pivot in one direction while being rigid in the other. It doesn't have anything to do with the angles between the points. It has everything to do with the ability for those angles to change.
I'd sure like to hear from the skeptics some plausible explanation for how they think the angle of the linkage can prevent a change in any of the angles at the 4 linked points?
As far as the pivot point, remember that a pull on one of the side links also involves a push on the other. Remove any contact with the ground from the equation and there will be a change in the linkage angle regardless of which end initiates the change.
