Bar Vibrational Modes

The elastic property involved in the vibration of bars is usually stated in terms of Young's modulus.

Clamped Bar Modes

The frequency f₁ depends upon the density and elasticity of the material from which the bars are made. The amplitudes for the f₂ and f₃ modes would actually be much smaller than the fundamental. These mode frequencies appear with a tuning fork since it can be considered to be two clamped bars.
