How does adding deliberate damping to a car's suspension system help improve its performance?
it prevents excessive vertical oscillations of the wheels over bumps.
it enables fine tuning of the natural frequencies.
it stores energy from vertical oscillations to reuse.
it transfers energy from vertical to horizontal oscillations.
|
Which effect of damping helps improve the performance of moving coil meters?
it allows higher amplitude oscillations.
it prevents needle oscillations.
it enables electrical damping adjustments.
it reduces internal energy losses.
|
What term describes a damping level that stops oscillations rapidly without oscillating?
light damping
underdamping
heavy damping
critical damping
|
How does damping affect the sharpness and height of an oscillating system's resonance peak?
it makes the peak shorter and broader.
it does not impact the resonance peak shape.
it makes the peak taller and narrower.
it makes the peak taller but does not affect width.
|
Adding damping to an oscillating system makes its amplitude response:
more sensitive to changes in driving frequency near resonance
more sensitive to changes in driving frequency away from resonance
less sensitive to changes in driving frequency away from resonance
less sensitive to changes in driving frequency near resonance
|
Deliberately damping a resonating system:
increases overall energy losses
narrows the resonance peak width
decreases sensitivity to the driving frequency
can enable finer tuning of the natural frequency
|
Adding damping to an oscillating system causes:
a lower resonant frequency.
a narrower, taller resonant peak shape.
a higher resonant frequency.
a shorter, broader resonant peak shape.
|
What is the term for opposition forces that remove energy from an oscillating system?
|
What aspect of an oscillation is reduced by damping forces?
|
What term describes very small damping forces in an oscillating system?
|
Give 3 examples of systems that use deliberate damping.
|
Briefly explain one advantage and one disadvantage of heavy damping in an oscillating system.
|
