Water wheel a chain basket (German: Kettenkorb) on the axle of the wheel. It is essential that the wheel have braking equipment to be able to stop the wheel (known as a braking wheel). The oldest known drawing of a reversible water wheel was by Georgius Agricola and dates to 1556. Two early improvements were suspension wheels and rim gearing. Suspension wheels are constructed in the same manner as a bicycle wheel, the rim being supported under tension from the hub- this led to larger lighter wheels than the former design where the heavy spokes were under compression. Rim-gearing entailed adding a
The Bicycle Wheel select components, how to build a wheel, and how to repair various forms of damage. Part three, 'Equations and Tests', provides a mathematical analysis of spoked wheels. "The Bicycle Wheel" is considered by many to be the premier resource on building bicycle wheels. Noted bicycle mechanic and technical expert Sheldon Brown called it "the near-definitive text on the theory and practice of building spoked bicycle wheels." The Bicycle Wheel The Bicycle Wheel is a treatise on wheelbuilding by Jobst Brandt. "The Bicycle Wheel" is an educational book that explains the structural theory of a wire wheel, and teaches the practical
