I'm struggling with a concept we are trying to run.
We have created a spring, cut from a cylindrical pipe and we wish to apply torsion so as to tighten it up, therefore reducing its diameter and increasing it's length BUT maintaining the same pitch.
The profile is a 1" wide rectangle and our aim is to ensure it maintains its pitch so that, in our application, we essentially wind it up to fit onto a smaller diameter and need to represent the two states.
Can this be done? I tried to figure it out using adaptive springs to give me the sizes I need but couldn't quite get it to work, so hopefully someone can shed some light on this for me!
I hope the image helps to show what I'm aiming to do.
