Motors

This volume offers a hands‑on tour of the machines that drive the modern world, from steam boilers to the first internal‑combustion engines. Written in plain language for a young audience, it breaks each component apart—illustrated with original, step‑by‑step drawings—so listeners can picture how pistons, valves, and turbines actually move. By explaining the reasons behind each design choice, the book equips aspiring builders with the knowledge needed to diagnose and fix everyday engines.

Separate sections explore the mechanics of automobiles, detailing carburetors, ignition systems, and electrical circuits, then move on to early aircraft, describing lift, control surfaces, and the differences between mechanical flight and bird flight. The text also touches on wind and water motors, compounding, condensing, and power‑transmission calculations, giving a rounded view of how energy is generated and used. With clear explanations and vivid illustrations, listeners gain both a historical snapshot of early 20th‑century engineering and a practical foundation for future tinkering.
