What is it? The axle is a long skinny rod that attaches to the center of a wheel, gear, or pulley. When the axle turns, whatever is attached to it also turns. This makes it possible to transfer rotational motion from one axle to another with gears or pulleys. Give me an example! In the picture above, you'll see a good example of how axles can work together with gears and pulleys to get your project rolling! |
