Resonace Frequency of Bodies/Materials

    Hi there,

    I'm would like to know how to calculate mechanical resonance frequencies of material and form. ie. the materials i'm choosing first are glued wood, as they are much easier to cut/shape. The form would be shaped into an inverted funnel like or bell shaped of different sizes and hollow on the inside. The ideal thickness would be around 1 to 2 cm.

    Firstly how do i go about calculating mechanical resonance frequency of wood and most importantly how does the size and shape of the form effects the mechanical resonance frequencies? How do I determine the factors involved?

    Briefly- I would like to have a tuning fork, being place on the form to create harmonic resonance frequency, not only a louder sound, but also the right frequencies that will vibrate the body, hopfully to create harmonics.

    naturally i can do a trail and error method, but as this work is rather strenuous, i would like some form of formula to determine what will happen before i start the partical work.

    any form of help would be greatly appreicated.

    Dennis I dont know what level you are at but you seem to have chosen very difficult shapes and material to investigate the difficulties being both theoretical and experimental.May I suggest that you go for something simpler.

    hi there,

    thanks for the link <atyy>. this is almost something i'm looking for.

    yes <DadFace> you might be right, this will take some time and experimentation to build.

    I will write with more about my findings and questions.
