Bicycling Science

by David Gordon Wilson

Published 1 January 1974
The bicycle is almost unique among human-powered machines in that it uses human muscles in a near-optimum way. This new edition of the bible of bicycle builders and bicyclists provides just about everything you could want to know about the history of bicycles, how human beings propel them, what makes them go faster and what keeps them from going even faster. The scientific and engineering information is of interest not only to designers and builders of bicycles and other human-powered vehicles but also to competitive cyclists, bicycle commuters and recreational cyclists. The third edition begins with a brief history of bicycles and bicycling that demolishes many widespread myths. This edition includes information on recent experiments and achievements in human-powered transportation, including the "ultimate human-powered vehicle," in which a supine rider in a streamlined enclosure steers by looking at a television screen connected to a small camera in the nose, reaching speeds of around 80 miles per hour. It contains completely new chapters on aerodynamics, unusual human-powered machines for use on land and in water and air, human physiology and the future of bicycling.

For senior/graduate-level courses in Turbomachinery.

One of the only texts to focus on turbomachinery and gas turbines from the "design" point of view, this volume reviews the necessary thermodynamics, gives extensive design data, provides engine and component illustrations (with comments on good and less-than-good design features), and contains many worked examples - allowing students to produce preliminary designs that can be made and run quickly -as early as Ch. 5. More comprehensive than similar texts, it features a simplified - and more accurate - thermodynamic treatment that eliminates the confusing use of "gamma" and specific heat together, and provides individual full-chapter coverage of on axial-flow turbines and compressors and radial-flow versions of the same.
