Homework Statement
x''+b*x'+k*x=k*y+b*y' y=cos(omega*t)
k is fixed, b - damping constant slowly increases.
How does increasing the damping constant b affect the resonance peak?
2. The attempt at a solution
Well, I thought the answers:
It significantly decreases the height of the resonant peak.
and
It significantly decreases the frequency at which resonance happens.
are correct.
I have found a useful resource - http://physicsnet.co.uk/a-level-physics-as-a2/further-mechanics/forced-vibrations-resonance/
But these answers were marked as wrong. I have no idea why. What have I missed? Is it possible that this option is correct: It does not significantly change the shape nor the location of the resonance peak.?
