Hookes law

  1. Sep 17, 2007 #1
    Help me??

    I need to find three different names for the constant between length and force in hooke's law. I also need to find out why, when rubber bands are stretched by force, at a certain force, they actually get shorter. can anyone help?

    1. The problem statement, all variables and given/known data
    I need to find three different names for the constant between length and force in hooke's law. I also need to find out why, when rubber bands are stretched by force, at a certain force, they actually get shorter. can anyone help?


    2. Relevant equations



    3. The attempt at a solution

    the only idea i have for why it gets shorter is because of temperature when the band is streched out. but i have no idea if that is accurate.

    Let's see, Hooke's law often deals with a spring under force. Look up each of these words as partial terms for the constant in your physics book. Stiffness (check it out first so you can back it up) is a term that might wow your professor.

    Get shorter? It's a critical point where the band permanently deforms. See if your book yields the answer.
