About

Hanging chains and shapes of suspension bridges. The designs of some of the world's greatest bridges. The shapes of arches and domes. The shapes of the Eiffel Tower and the Swiss Re Tower (the 'Gherkin'). The design and efficiency of windmills. Why do the wind turbines have an odd number of propeller arms? The problem of building a roller coaster that doesn't subject the rider to lethal g-forces. The special properties of the clothoid curve and its use in the building of fairground rides and motorway junctions.
