Hensley Arrow: How does it REALLY work?

This must be where the theory of "dumbed down" is coming from...

There is no appreciable loci of ellipse when pulling, because there is no pivoting, no translation, and the connection is as rigid as a steel bar can make it. There is a loci of ellipse when backing up or turning.

And of course you're not pulling when you're turning...

You said, "Since 'C' is imaginary, the only force that can be applied to it is an imaginary force. Forces act on bodies." I say, "The hitch receiver is on the way to point C, lend me a portion of your anatomy to use as a shim in the receiver, and you can talk to me about your imaginary forces while I crank the come-a-long." (I have a portion of your anatomy in mind. :B).

Very cute.

Translation only occurs if C moves left or right, and that only happens if C is moved left or right by the steering mechanism of the truck. What I have been trying to get across is that there is no translation when the TV is pulling the TT.

Lucky students. You're so anxious to talk that you cannot listen. The Orange part of the hitch will initially and ONLY be translated left or right upon initiation of any turn, in any direction, going forward or backward from a straight line between the TV and TT. I think that's exactly what I said earlier, but maybe the way I said it was faulty. P.S. Nobody learns much of anything when they're talking.

You will destroy the hitch before it will translate a millimeter. The linkage does not bend, shift, wiggle, or anything else from the TT end, it is as if it were constructed of a rigid steel bar. (It is).

Actually, it isn't.

Stressor wrote:
The black part, the TV end, moves as points DE move in the diagram above, if and only if the TV is turned. The black part moves not at all if the trailer provides the input.

This much is absolutely correct. But then you go off the reservation, so to speak...

This is called a locked linkage, and believe me, it is locked.

We used to have a saying when I was flying (nearly 40 years ago) called head down and locked. I won't bother to explain...

Stressor wrote:
(See the picture with the come-a-long). I think we said the same thing, and it appears that you did say that the translation is a sideward movement.



Please point out any translation you see in the photo above.

I know all about Adam Smith. This ain't like that, this is about how a linkage works. Start a thread about whether or not the Hensley is worth it or read the 55 that already exist.

Question is whether or not chasing this particular rabbit down the hole is worth pursuing. It's kind of like trying to teach a pig to dance. Before long, you begin to realize that the pig likes it!..

Anyway, Read some more of Mr. Gertz. I for one am glad he's back. We can all learn from each other, but only when our brains are unlocked.

Sincerely and respectfully,
