Damping Ratio

  1. Dec 1, 2009 #1
    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.
