Understanding Vibration and Resonance

2 жыл бұрынWatch the companion video on pendulums here: nebula.tv/videos/the-efficien...
In this video we take a look at how vibrating systems can be modelled, starting with the lumped parameter approach and single degree of freedom models. We then go on to look at damping, the dissipation of energy that occurs in all real systems, as well as forced vibration, resonance and multiple degree of freedom models.

ERRATA:
- At 04:16, the terms sqrt(k/m) appears not in the equation of motion, but in the solution to the equation of motion

One really needs to learn the forced damped oscillator, it covers a lot of physics. It's an algebraic equation in the frequency domain, it's totally diagonalizable in multiple dimensions, and it forms the basis of perturbation theory for non-linearities.
