Thanks for your reply and I appreciate your help as online material is confusing and inconclusive!
I am interested in a connector that behaves such as a hardening sping. As it deflects more, rates increases. In addition, there is geometrical limitations. Maximum OD is 0.5" and minimum ID is...
Please let me know what kind of options I have to purchase a nonlinear connector? Conical springs might be an option, however, I am more interested in a rod shape compression spring that has a variable rate.
Thanks
