Reference to theory needed for cylindrical pull geometry
Cylindrical pulling is a non-trivial thing in terms of the theory but the manual is very scarce on it.
If one googles it is possible to find information that such pulling causes non-trivial radial forces, but there is no derivation of them anywhere. I failed to find any dedicated paper which details on this pulling geometry, which means that it is currently a "black box".
If the paper on this topic exists the reference should be added to the manual. If not, than the theory should be given briefly in the manual itself.
