This paper focuses on: chains, sprockets, belts, pulleys, ropes, cables, and other such things. The same ideas here can apply to all of them. To grasp this paper, you only need basic work or life events. If you: took off a bike tire, looked at a bike chain, worked on a minibike, replaced a car belt, or saw a pulley system, then you already know enough to follow what will come next. This paper does not focus on: gear ratios, speed, or torque. This paper looks at: contact area, tension, slip, wobble, and control. The main idea is simple: Do what works.
