Hi there I need some advice, please: can you suggest any interesting cases of a driven, damped harmonic oscillator? I need to write a report (part of some assignment) on the mathematical model/behaviour/etc. of some real-world driven oscillator. No problems with the math, I'm just looking for an interesting model. By interesting I mean: not a driven mass-spring system! Also, I don't want to get into anything quantum-mechanical - it's not a physics assignment, and there's not really scope in the assignment to venture beyond a straightforward classical model. An example might be some sort of car shock absorber, the "driven" part being on account of a bumpy road...presumably resonant oscillations would be undesirable! But any better suggestions? Thank you!
