What is Forced Vibration?

Forced vibration occurs when a system is subjected to an external periodic force, causing it to oscillate at the frequency of the applied force rather than its natural frequency. This type of vibration can be seen in systems like machinery, where external influences, such as motors or seismic activity, induce motion. The response of the system depends on factors such as the amplitude of the applied force, damping characteristics, and the mass of the system. Unlike free vibrations, which occur without external influence, forced vibrations can lead to steady-state conditions where the system oscillates continuously at the driving frequency.

How to Calculate Complementary Function?
