Are you in engineering? I'm a 4th year mechanical myself at the University of Saskatchewan.

I agree with you there, that property is called hysteresis (sp?) I believe. Learned some about that in hydraulics since it affects how relief valves (and other things with springs) open and close with pressure. However, I think you could still set the band to have the same linear effect either way. You would just have to have a little more pretension when using it in the unloading direction. (band is lifting the weight). Anyways, I didn't think the hysteresis of the band would be a large enough effect to consider but I've also never tried it before!

I'm finishing up a master's degree in structural engineering.

It is a type of hysterisis. Hysterisis loops are usually generated from numerous cyclic loadings. The effect can be large depending on the strength of the band and definitely on how much strain you've induced in the band.

Why do I get the feeling you guys can't express this in english? I'm not sure who's agreeing or disagreeing with what.

If you act sanctimonious I will just list out your logical fallacies until you get pissed off and spew blasphemous remarks.

The scary part is that was english

I think somewhere along the lines it turned from a powerlifting topic to a discussion of introductory mechanics of materials

Introductory?? I'd hate to see what it's like when it gets complicated...
