Can a torsion spring be twisted in both directions without weakening it?
In other words, can it be twisted in the direction of tension (thus slightly reducing it's diameter), and also be twisted in the opposite direction which would thus increase or expand the diameter? With out pre mature failure? Or are most such springs only designed to be twisted in direction of compression (smaller diameter)?
I have an application for a 180 degree torsion spring, I would like to twist it 90 degrees in either direction...
Thanks for any input.
