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 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 methodology of building bicycle wheels. The book is made up of three parts. Part one, 'Theory of the Spoked Wheel', examines how a wire wheel supports various loads, what causes wheel failure, what aspects of a wheel confer strength and durability, discusses each of the individual components that make up a spoked wheel, and examines wheel design. Part two, 'Building and Repairing Wheels', explains how to
