On the dynamics of Tuning Forks. (Rossing, Russell, and Brown 1992)
Characterizing Tuning Forks Aluminum, tines 10mm apart. Four main groups of vibration:
Symmetrical In-Plane Antisymmetrical In-Plane Symmetrical Out-Of-Plane Antisymmetrical Out-Of-Plane (a) and (c) are in the first group; (b) is in the second group, where the fork just warps.
Deriving Tuning Forks&rsquo; Frequency As per before, we can treat tuning forks acting in clang and fundamental modes as a good&rsquo;ol fashioned cantilever beam.
The frequency action of a cantilever beam is defined as follows:
Otherwise, for asymmetric modes, we can use the same exact expression but with uniform rods unfixed at either end:
Note that density is not uniform at this point (because the bottom handle-y bit.)
