Why do we need forced vibration?
The vibration of moving vehicle is forced vibration, because the vehicle's engine, springs, the road, etc., continue to make it vibrate. Forced vibration is when an alternating force or motion is applied to a mechanical system, for example when a washing machine shakes due to an imbalance.
How to Calculate External Periodic Disturbing Force?
