Wave Propagation in a Coil Spring

  1. Jun 25, 2012 #1
    I am studying the vibrations in a coil spring, and want to confirm with others that my derivation is correct.

    I found that for small oscillations the spring is described by the 1-D wave equation, with wave speed k*l^2/m. where k is the spring constant, l is the spring length, and m is the spring mass. Does this sound familiar to anyone?

    Just looking at the dimensions, it should be square root of that.
