How Machines Work : Timeline

One of the most fun & interesting parts of the How Machines Work book project was working on a timeline which runs throughout the book. I produced around 60 illustrations showing how the different types of simple machine have been applied throughout history. Here is a small preview showing a Steam Engine with Sun & Planet gears (gears), Rack Railway (Rack & Pinion), Mesopotamian Wheel (axle), Corkscrew (Rack & Pinion), Rollercoaster (Ratchet), & Sumerian Potters Wheel (axle).
