News:
 I have added the derivation of the wave equation (pdf). Have a look at this over the weekend so you can have a sense of what it is and places where you would like clarification.
 I have posted guide 4 and solutions for all three problem sets.
 The 2019 "Official 195 Measurement of g" is g = 9.84 + 0.08 m/s^2.

 Our derivation for transverse waves on a string.
 The Citicorp Center in NYC and the Taipei 101 Tower have tuned mass dampers. A book by Kohn, Katz, and Robertson has a schematic of the Citicorp Center mass. The building is 279 m high and has a period of around 6.5 s.
 Here's a pendulum in the Taipei 101 Tower. For more specifics see this article and "Wind and Earthquake Resistant Buildings", some of which is on google books.
 Here's the PhET wave simulation.
 Here's the PhET normal mode simulation. (Requires Flash.)
 The results are in! The 2019 measurement for g on the Hill is g = 9.84 + 0.08 m/s^2! (This agrees with the previous average of 9.815 m/s^2. Given the variation in measurements I used the standard deviation of your results for the error.)
 The masses on springs videos: 1 and 2.
 A resonator exhibit at the Exploratorium.
 A video of a wine glass orchestra or harp.
 You can see more of the Tacoma Narrows bridge in this video.There's a 2006 American Journal of Physics article by Green and Unruh on a more careful modeling of the Tacoma Narrows bridge. (This link is to the arXiv where many physics papers are available to read without charge.) Last year APS News published a piece on this and the authors reminded us that the original accident report pointed out the nonresonant behavior of the bridge.
 Here is the Phet simulator on resonance.
 A XKCD comic on resonance.
 In class on Friday, February 8 we went through the `late time' or `steady state' solution of driven, damped, harmonic motion. Here are the notes (pdf) for the `brute force' approach of plugging the trial solution and working through the algebra.
 Millennium Bridge oscillation video.
 For a review of rotational dynamics see Chapter 10 of HRW.
 Galileo may have timed the swinging of the chandeliers in the Pisa cathedral. This one appears to be one of the "modern" ones installed in 1587.
 Here is the PhET spring massonaspring demo. Enjoy!
