WebHarmonic Oscillator Approximation 16.1 : 4/7 The harmonic oscillator approximation treats a diatomic as if the nuclei were held together by a spring. The potential energy of a classical harmonic oscillator depends upon the square of the displacement from equilibrium and the strength of the spring. All values of energy are allowed classically. WebJan 15, 2024 · One common cause of harmonic forced vibration in mechanical systems is rotating unbalance. This occurs when the axis of rotation does not pass through the center of mass, meaning that the center of mass experiences some acceleration instead of remaining stationary.
