The natural angular frequency ( at which this SHM takes place is proportional to the square root of the 'spring constant', Bp in this case, divided by the moment of inertia I of the bar. In the actual experiment a small additional contribution to the 'spring constant' arises from the torsion in the suspension wire and a correction has to be ...

The angular frequency is the “natural resonant frequency” of the system. The spring is displaced a distance A and released and then the mass . oscillates from displacement of +A to –A. At the maximum displacements, all of the energy is stored elastic energy, and the velocity is zero.

However, if the angular frequency of the driving force, d, is approximately the same as the natural angular frequency, , of the system, then the system experiences . resonance. When resonance occurs, the amplitude, xm, of the system reaches a maximum. There are many examples of …

The Rayleigh method gives a natural frequency that is an upper limited of the true natural frequency. The method would give the exact natural frequency if the true displacement function were used. The true displacement function is called an eigenfunction. Consider the rectangular plate in Figure 1. The largest dimension may be either a or b ...

and the angular frequency is given by: The subscript (“D”, for “damping”) helps to distinguish this angular frequency from the natural or free angular frequency, . Note that frequency of the damped oscillator, , is smaller than the natural frequency. For small damping one may neglect the shift.
