<br />
Positive locking is in essence about an energy barrier against <br />
* undesired disassembly or <br />
* undesired positional dislocation (not self restoring)<br />
such that these events [[FAPP]] can not happen by means of external perturbations like e.g. <br />
* mechanical shocks and shaking at any scale or <br />
* thermal motion near the nanoscale.<br />
[[FAPP]] means other effects would dominate fist.<br />
* Things would break elsewhere first from shocks and vibrations.<br />
* Things would melt first from the thermal motions .<br />
<br />
The only way to non-destructively change the configuration of positively locked systems <br><br />
is by brain rather than brawn. One has to go in there and "pull the right levers".<br />
<br />
Positive locking can give high reliability. <br><br />
It keeps things safely in [[machine phase]] even for enormous amounts of parts. <br><br />
(I.e. [[mol]]s worth of parts). Keeping [[non-thermal system entropy]] from increasing. <br><br />
