Free Vibration of MDOF Systems:

Free vibration take place at natural frequencies of the system and, in general, the motion will consist of several simultaneous oscillations at the various natural frequencies of the system.

However, under certain specific conditions, all the coordinates will undergoes harmonic motion corresponding to one of the normal frequencies of the system.

When such motion take place, the motion is called the principal mode of vibration, or the normal mode of vibration.
