Hensley Arrow: How does it REALLY work?

Tim et al.,

I don't think there is any significance that can be attached to the point of intersection between the centerlines of the TT and the TV.

There's only no significance if you disregard what it looks like to the layman from a birdseye view. I would submit that it is sometimes useful and helpful to provide descriptions to things even though they may not be considered "significant" for calculations or for understanding the primary interactions.

I have the Hensley video where they use an actual hitch for demonstration purposes. They show that when the TV tries to create an angle with the TT there is no resistance and the angle is easily created. Then they demonstrate that applying strong lateral forces to the TT side of the hitch results in no angle being created - Yes, the combo moves as a single unit. I don't know that that answers where the pivot point is so well, but it sure addresses the concern with TT induced sway.

Tim,

In a previous thread, I made several postings (running across two pages) offering my opinions on Hensley's "model" TV and TT coupled by a full size HA.

I would appreciate your comments on my remarks since you have seen the video and I have not.

You have a remarkable understanding of how the Hensley works considering that you haven't even seen the video. In the demonstration on the video, the guy only pushes laterally on the front of the TT tongue portion of the model. The only other thing he does is go to the front of the TV portion of the model and rotates it to simulate the TV turning the TT. I have snapshots that I just took off of a video capture that I'll post on here next.
