Rubber Bands . A rubber band is just a kind of spring. A rubber band is slightly more versatile than a metal spring because of its flexibility, just as pulleys are more versatile than their rigid cousin the lever. Using springs in ELEC 201 might take a small amount of imagination, but rubber bands almost scream to …
