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