Hello,
I have to accelerate a 4 kg mass to a velocity of 15 m/s. The maximum length of the launchpad should be 2 meters.
When i use a spring, i need to take one with an initial length of more then 10 metres to achieve a stroke of 2 metres. I know that some polymers have the ability to stretch for a 100% or more. The only question is: which materials can i use for that without having plastic deformation? (including creep)
thank you.
