extrapolating the Quality factor for decay in amplitudes

mercredi 17 septembre 2014

1. The problem statement, all variables and given/known data

By what factor does the amplitude decay in the time interval (which I had to find).



E: stored energy

γ:damping rate

a: amplitude

t: time

Q: quality factor

T:Period

ω: frequency



2. Relevant equations



Q = 2∏E/(ΔE)



3. The attempt at a solution

I found the interval to be t=QT

but "one cycle" indicates T=2∏?



So I'm not exactly sure if I got the right answer for the quality factor by which the quality factor decays? I feel like there is supposed to be a numerical answer. Any insights? Did I mess up anywhere or took the wrong approach? Anything will help!



Thanks!
