Thanks, I was more looking for an equation(s) which allows me to input the physical dimensions of the piston and the viscous fluid in order to calculate the damping coefficient, rather than recorded data of the damper performance.

Hi all, I am trying to calculate the damping coefficient of a linear viscous dashpot/damper given the dimensions of the piston, and the dynamic viscosity of the damping fluid. I have found this calculator, but does anyone know the equation that it uses...

OK, thanks. Going right back to basics - I've been told that there is a relationship between the frame rate which the camera is recording at, and an upper boundary of vibration frequencies, above which they will not be visible, explained(?) by Nyquist. Is this correct? Sorry for the ignorance...

Thanks for the reply. Does this mean that if I isolate the vibrations below 15Hz, no other vibrations will be apparent?

Hi everyone! Struggling to get my head about Nyquist's Frequency.. Have I got this right? The Nyquist Frequency is 1/2 of the sampling rate of a discrete signal, and is the highest frequency that will allow a signal to be fully reconstructed without aliasing, at a given sampling rate. The...
