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 video (the fourth of four) shows how to operate the machine. Check out the series companion book and learn how to get a free PDF of the entire book at http://www.engineerguy.com/fourier.

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.
