MIT Vibrations and Waves Problem Solving Help Videos, Fall 2012 - 2. Harmonic Oscillators with Damping

View the complete OCW resource: http://ocw.mit.edu/resources/res-8-005-vibrations-and-waves-problem-solving-fall-2012/ Instructor: Wit Busza In this session, we extend the solution of the motion of oscillators with one degree of freedom without damping to the case where damping can no longer be ignored. *NOTE: These videos were originally produced as part of a physics course that is no longer available on OCW.* Chapters 0:00:00 Title slates 0:00:23 Harmonic oscillators with damping overview 0:02:54 Definition of the quality factor Q. 0:04:40 Calculation of Q for the "hanging ruler" oscillator considered in the first example. 0:07:43 A general discussion of all possible harmonic oscillators with one degree of freedom, with or without damping, based on the three cases considered earlier. 0:13:12 The motion of the ruler if the damping is weak ("under-damped" case) 0:13:54 The motion of the ruler if the damping is strong ("over-damped" case). 0:15:59 Oscillation of a hanging ruler pivoted at one end.
