Hello all,

I have a physical problem that I am trying to understand. Please see the attached schematic.

I would like to rotate a tubing 'x' degrees, and then apply an axial displacement within that rotated plane so that the tubing is constrained in the new "out of plane" direction only... in other words, it slides within a frictionless layer (pink/salmon colored) and can do whatever it likes within the above layer (this is what I am interested in). The grey block that is fixed that the tubing goes through is a fixed support, as there is no sliding allowed within there and is much stiffer compared to the tubing. Additionally, I would like about ~ 1" or so until it enters in the pink/salmon colored layer ( I eventually would like to alter this).

This can buckle, so I would imagine it not being confined to axisymmetry.

How can I optimize and simplify this problem? Can I having an extra tubing attached to the real tubing to emulate the pink/salmon colored layer, rotate about the face closer to the grey block, and then lock this outer tubing AFTER rotation? Would assume fricitonless behavior.

Any thoughts on this would be greatly appreciated.

Kind Regards,

Zach
