This a more or less theoretical question:
Given some pipes freely hanging from a wire?,fishing line? or ...?, what could be the most elementary set up to measure their natural frequency when hit with a solid object?
I am talking about pipes open at both ends. I am basically aware that dimensions and resonant frequency ar closely related but I am not so familiar with common terms like "overtones" and the like.
My interest is focused on the setup to measure the resonant frequency or whatever is the name you give to that.
A small mike connected to an oscilloscope (not a DSO!) could help, I think, but since vibration is attenuated so quickly (for small pipes) how could I measure it reliably?
My bench is not fitted with sophisticated equipment, just a 10 MHz dual input scope.
Thanks for any reply.
