Bonus: Rocker arms: sinusoids in two different directions

This series on Albert Michelson’s Harmonic Analyzer celebrates a nineteenth century mechanical computer that performed Fourier analysis by using gears, springs and levers to calculate with sines and cosines—an astonishing feat in an age before electronic computers. This bonus video shows the motion of every rocker arm -- that is, every sinusoid. The end of the video shows all the arms in motion together.
