I'm working on a project where I need to hang an object which needs to move vertically as you pull it down. The longer it bounces the better it is. At this point, there is no clear reason to avoid metal - just looking for alternatives if any. I hope this is clear.
Hi everyone,
Any alternatives you know for metal spring? The idea is to find a replacement for a metal spring that has the same efficiency in bouncing an object that's hung by the spring. Any input of a kind would be valuable.
TIA
