external periodic forces
|
What is the term used to describe the external frequency applied to a system undergoing forced vibrations?
driving frequency
natural frequency
damping frequency
vibrational frequency
|
When does resonance occur in an oscillating system?
when the driving frequency is much higher than the natural frequency
