So, in a car either a liquid or a gas gets compressed when force is applied to the suspension, and when the force is removed the gas/liquid tries to expand again which makes an effect like a spring,
But could you make the opposite, or does it already exist? so a pull creates a vacuum (or just lower pressure), when the pull is stopped the vacuum (or just lower pressure) will try and pull back, and work like a spring?
While waiting for answers i googled a bit, and what Ι could find was something called gas springs, but these only seem to be for dampening and only suspension? or can they also be used for pull and retract like a normal steεl spring?
Thanks in advance for information. (:
