Simple Guide is about the mechanics hiding in plain sight: the lever on a handle, the teeth inside a gear train, the threads that keep a fastener in place. It is for curious readers who want to understand how familiar objects work without needing specialist vocabulary as a starting point.
What we cover
We explain basic mechanical principles and the parts that put them to work, including levers, gears, pulleys, fasteners, and mechanisms that change one motion into another. Each subject is chosen for its usefulness beyond a single object: understanding a principle can help make sense of many designs.
Who this is for
The site is for anyone who has looked at a moving part and wondered what makes it work. No technical background is assumed. Terms are introduced when they help explain a mechanism, and the explanation stays focused on understanding rather than specialist training.
How we explain
We start by identifying the parts and their roles, then trace what happens when one part moves. Definitions and examples are used to make the principle visible. We distinguish a general explanation from instructions for a particular product or repair, and avoid presenting basic descriptions as a substitute for qualified help where it is needed.
