Homework Help: Tubular bells

  1. Oct 31, 2007 #1
    I have the next theoretical-practical problem. I have to build a tubular bell array (like that at symphonic orchrestas) with tubes (not rods) of aluminium or copper. The principal problem I have is I don't know how to state the wave equation for a tube (I have done it for a string). How I do it?

    When I have the wave equation stated I must get the frecuencies to get a standing wave. Obviously this is what I want.

    Could you help me?

    If the bells are open at both ends, the wave equation is the same as for strings.

    Ok but of what quantities the velocity of propagation depends on that's my problem.

    The velocity of propagation is the velocity of sound.
