How can I calculate the theoretical spring constant using physical parameters?

[drdizzard]

I'm working on a lab and part of it requires the calculation of the theoretical spring constant of a spring based on its physical parameters and compare it to the spring constant calculated experimentally. I can calculate k using my experimental data fine, but I can't find anything on calculating it based on physical parameters. Any help would be appreciated.

Don't you have a textbook (e.g. Shigley) that includes the equations for spring design? By the way, this sounds like homework and therefore should be in the homework section of the forum.

What do you mean physical parameters?

Size, shape and material used?
