KootK - hopefully, you will see this. I found this video from the same guy who had the tension instability video.
As I commented on the video, it seems if you add rotational stiffness to the rollers, it you could build up potential elastic torsional energy in the bar that would propel the bar at an even greater acceleration than the demonstration in the video shows. Like a modern and more compact catapult...or dare I say gun.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

1. I'm still not sure what an "Eshelby Like force" is.
2. Where does this force come from? Does it require the tangent to the contact point to be non-vertical, hence the need for non-tight fit?

It seems that the answer to Question 2 is yes.
