Yes, but it involves a second order differential equation. Using the mass, spring constant and damping constant any physical object or assembly's damping ratio can be calculated. In the design of the vehicle the damping ratio was determined by the engineers at the automaker depending on the type of car. A sports car would have a higher damping ratio (maybe 0.7 or so) than a cushy luxury car. Over time the damping ratio will change as the components age. The most obvious is the bouncy feeling when you don't replace your struts or shocks as intended. That's when your tight sports car's suspension starts to behave like a 70's Buick. You just lowered your damping ratio without knowing it.
Geometric damping is also called radiation damping. It is defined as energy radiation into a surrounding medium. Damping is defined as energy dissipation property of structures and materials that are put through time-variable loading.
Decibel is a factor or a ratio and no unit. If you have 1 volt and you damp it to 1/4 volt then you will get a damping of 12 dB. Voltage daming = 20×log (1/4) = (-)12 dB.
Because of air damping.

the fine boring spindle using CBN tools creates chatter . is it because less damping ratio of spindle? the bore is 100 mmdia . L/D ratio is 5
Transformer Z-ratio = (Zpri / Zsec) = (Vpri / Vsec)2 It could also be the damping factor DF = Zload / Zsource The damping factor DF is the load impedance Zload (input impedance) divided by the the source impedance Zsource (output impedance).
It is the opposite of normal damping (oscillation decreases), so in negative damping to get even bigger oscillation.

The amplitude of resonant oscillations can be reduced by damping.Light damping reduces oscillations slowly.Heavy damping reduces oscillations quickly.Critical damping stops the oscillation within one cycle.The graph above shows light damping.
critical damping is when the amount of damping is large enough for the system to return toequilibrium as fast as possible without performing oscillations. Hope thatHELPED

No, a pogo stick is not a critically damped system. It typically exhibits underdamped behavior when bouncing, with oscillations that gradually decay over time due to damping effects. The damping in a pogo stick is usually not enough to make it critically damped.
Geometric damping is also called radiation damping. It is defined as energy radiation into a surrounding medium. Damping is defined as energy dissipation property of structures and materials that are put through time-variable loading.
In the damping level the level view and vertical spindle are crossed together...
The larger the surface area, the larger the damping of an oscillation
