The mathematical formulation of this question involves the Dirichlet eigenvalues of the Laplace equation in the plane, that represent the fundamental modes of vibration in direct analogy with the integers that represent the fundamental modes of vibration of the violin string.

The appropriate drive levels are about 5 ?W for flexural modes up to 100 kHz, 1 ?W for fundamental modes at 1 4 MHz, 0.5 ?W for fundamental modes 4 20 MHz and 0.5 ?W for overtone modes at 20 200 MHz.

Okano's group experimentally correlated the shear modulus to the frequency of standing shear modes using mechanical resonance techniques in the oscillatory experiments at lower frequencies ( < 40 Hz ), the fundamental mode of vibration as well as several higher frequency partial overtones ( or harmonics ) have been observed.

The " a priori " is here nothing more and nothing less than a fundamental mode of thought, which I also call the finite mode of thought : something is already given to us in advance in our faculty of representation : certain " extra-logical concrete objects " that exist intuitively as an immediate experience before all thought.

A varactor, a diode with capacitance depending on applied voltage, is often used in voltage-controlled crystal oscillators, VCXO . The crystal cuts are usually AT or rarely SC, and operate in fundamental mode; the amount of available frequency deviation is inversely proportional to the square of the overtone number, so a third overtone has only one-ninth of the pullability of the fundamental mode.

For " regular " low-rise buildings, the structural response to earthquakes is characterized by the fundamental mode ( a " waving " back-and-forth ), and most building codes permit design forces to be calculated from the design spectrum on the basis of that frequency, but for more complex structures, combination of the results for many modes ( calculated through modal analysis ) is often required.
