Springs in Series

  1. Nov 21, 2009 #1
    1. The problem statement, all variables and given/known data
    I am trying to derive the effective spring constant of two springs, with different spring constants, in series. I know the equation is everyone online, so the effective spring constant is k1k2/k1+k2.

    So the question is, when deriving it, the force exerted on each spring is constant, why is that?? :confused:

    2. Relevant equations
    Hooke's Law -> Fx = kx

    3. The attempt at a solution
    Is it because of Newton's third law? If so, how does that work?? Force of mass on spring 2 is equal to force of spring 2 on spring 1? So the force acting on each spring is Fg??:confused:
