Hi, I just have a problem dealing with the background of a project im working on in physics...(adsbygoogle = window.adsbygoogle || []).push({});

I basically have a rubber band fixed at a point above the ground, from which I have masses suspended from it. So obviously, as I add more mass, the elastic is strained more and more, and stretches to a point where it finally just snaps. Anyhow, in this particular situation, how exactly would I figure out the maximum tension (or ultimate strength) before it fractures? Is it just a matter of T=mg? Or F = k/\L? (Hookes law) if you argue that elastics are considered springs...in which case, how would I determine a constant of proportionality?

thanks
