Extension spring question
Extension spring question
(OP)
Is it possible for an extension spring to be 20 inches long while unloaded, 32 or so inches long fully extended(12" max displacement), and have an initial load of 30-40 lbs? All other properties are virtually not important. If so, where could I buy them?

I would expect this to have a minimum core diameter, or perhaps maximum OD with spring wire diameter? What about material? If the extension is a foot, what sort of load is required given a preload of 40 lbf?

Get a copy of Machinery Handbook and look a t their excellent spring design section.
I took a peak and can tell you you re talking about 250 turns of 0.1055 dia wire with an outside dia of .533 inches ( very low index) with minimal initial tension, 100,000 psi at max extension.
