By assuming that the prongs behave like cantilever beams in bending, beam theory can be used to derive a formula for the natural frequency of the fork.
Understanding Vibration and ResonanceThe density, length and cross-section of the prongs can be calibrated to obtain the desired tone.
Understanding Vibration and ResonanceI can't actually get the fork in there at all. So to make this experiment possible, I'm going to bend the prongs on this fork so that they fit perfectly into the outlet.
