Determining Damping Ratio for Spring-Damper System

AI Thread Summary
The damping ratio for the upper spring-damper system can be determined using the formula r2/(2*sqrt(k2*m2). The discussion emphasizes that r2 is the only damping constant relevant to this calculation. Additionally, the time constant may be a simple ratio or a product of k2 and r2. Clarification on the specific parameters involved in the system is requested for more accurate calculations. Understanding these relationships is crucial for analyzing the system's dynamics.

Hi, my question is about determining the damping ratio for the upper spring-damper part of the system given in the link. Is it still r2/(2*sqrt(k2*m2)) or something equivalent should be determined?

Please be more specific. I think the only damping constant is r2 and the time constant is either a simple ratio or product of k2 and r2.

Thread 'Gauss' law seems to imply instantaneous electric field'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Highway: Deriving speed from Doppler shift'

I passed a motorcycle on the highway going the opposite direction. I know I was doing 125/km/h. I estimated that the frequency of his motor dropped by an entire octave, so that's a doubling of the wavelength. My intuition is telling me that's extremely unlikely. I can't actually calculate how fast he was going with just that information, can I? It seems to me, I have to know the absolute frequency of one of those tones, either shifted up or down or unshifted, yes? I tried to mimic the...
