Phase difference of damped oscillations

  1. May 29, 2014 #1
    1. The problem statement, all variables and given/known data


    i cant understand why curve above is for under dampling and the below curve is increased dampling. can someone explain please?

    Hello K,

    Yes, but in order to help you better, some more context would be useful, so please share your own considerations and also give a clue as to where you are in knowing about forced oscillations, resonance, etc. After all your picture comes from somewhere where there is more to be found...

    In the mean time: for f < f0 it seems pretty intuitive to me that more damping means that the driven oscillator is lagging behind more: it is being held back, so to say. And then continuing to higher f that tendency has no reason to change.

    i cant upload the photo directly to this forum . i also dont know why. can you take some time to explain this? i read a lot of online notes but i cant find out why the curve above is for under dampling and the below curve is increased dampling
