NARRATIVE
            There is a slide-type device apparatus with a set of gears and a crank which are designed to illustrate the comparison of uniform circular motion and simple harmonic motion. Place the slide on the overhead projector. When the crank is turned, one spot traces a circle while the other traces simple harmonic motion along the diameter.
