Spring selection

  1. Oct 22, 2009 #1
    For Intro to Design I am working a problem where I need to find the volume of a spring. The instructor hinted that you CANNOT use volume of a cylinder and subtract inner diameter. Please help. Thanks

    What information is given in your problem statement?

    NVM got it the formula for vol is =(pi*d^2)/(4)*pi*D*Nt

    Nt=# of turns

    Let me ask you this though any insight in what you consider design goals for springs with static loading?

    Well off of the top of my head I would say the spring constant, material (e.g. will it be used in a corrosive environment), and dimensions. Probably some more that I can't think of right now!

    On top of what Stewartcs mentioned, free height vs. solid height vs. working height are very important. Also, in static springs, stress relaxation is always a concern.
