Molecular dynamics simulations are typically run simulating extremely high speeds thus showing jelly like wobbling which would not at all occur when operated at actually proposed (steady state) speeds many orders of magnitude slower.

Be aware that:
⚠️ Diamondoid nanoscale machinery is not at all jelly like floppy
as molecular dynamics simulations may misleadingly suggest.
This is NOT what "gum" in "gem-gum" refers to. High simulations speeds are to blame.
For details see: Misleading aspects in animations of diamondoid molecular machine elements
Actually at nominal proposed speeds (few mm/s)
nanomachinery bends and deflects LESS from machine motions
than even everyday metal macroscale machinery does.
That is due to the scaling law of same relative deflections across scales.

A better intuition: hyper-spring-steel, super-magnets, and sometimes giant forces, all at snail speed
