Find the damped frequency of a tractor seat given the natural frequency is 20 Hz and the damping ratio is 0.5.

Find the damped frequency of a tractor seat given the natural frequency is 20 Hz and the damping ratio is 0.5. Correct Answer 17 Hz

ωd = ωn√(1-ζ2) Where ωd – damped frequency, ζ – damping ratio and ωn – natural frequency = 20 √(1-0.52) = 17.32
