"WebMETHOD The basic idea underlying Rayleigh’s method is that the motion of an undamped elastic system in one of its natural modes can be approximated by that of a single-degree-of-freedom system. For simplicity, I will refer in this section to the fundamental (1st) mode defined by the circular frequency ω0 = 2πf0. " - Rayleigh method in vibration
