Linkage Mechanism Designer and Simulator Orbit Machine Tutorial

Gears and chains are hard to use in the Linkage program. This tutorial uses both in a sun/planet/moon orbit system. Chain from the sun drives a sprocket at the planet which in turn makes the moon orbit that planet. Later in the video, another gear is added to change the direction of the moons orbit. Keep in mind that the Linkage program doesn't treat gears, sprockets, pulley's, all as separate elements. There is just the one gear element that is used in place of those things. Sorry if the tutorial sometimes switches terminology in a confusing way.
