Elastic forming a helix

  1. Jun 26, 2011 #1
    If I have an elastic formin a helix which i've turned N times and have a radiu r... it connect two masse m (one of them is fixed) - the natural lenght of the ropes are X_0 (the distance between the masses)
    what are the equation of motion X(t) and (Theta)(t) ??

    this masses are cirular of radiu r, that is: I=mr²
