1
Q
What is meant by forced vibrations
A
- Vibrations are forced when periodic force is applied
- frequency determined by frequency of driving force
2
Q
What is meant by resonance
A
Resonance when frequency of applied force = natural frequency
- when vibrations of large amplitude produced
3
Q

A
When force opposed motion
4
Q
