Excerpt from Bicycles Tricycles: An Elementary Treatise on Their Design and Construction With Examples and Tables A bicycle or a tricycle is a more or less complex machine, and for a thorough appreciation of the stresses and strains to which it is subjected in ordinary use, and for its efficient design, an extensive knowledge of the mechanical sciences is necessary. Though an extensive literature on nearly all other types of machines exists, there is, strange to say, very little on the subject of cycle design; periodical cycling literature being almost entirely confined to racing and personal matters. In the present work an attempt is made to give a rational account of the stresses and strains to which the various parts of a cycle are sub jected only a knowledge of the most elementary portions of algebra, geometry, and trigonometry being assumed, while graphical methods of demonstration are used as far as possible. It is hoped that the work will be of use to cycle riders who take an intelligent interest in their machines, and also to those engaged in their manufacture. The present type of rear-driving bicycle is the outcome of about ten years' practical experience. The old Ordinary, ' with its large front driving-wheel, straight fork, and curved backbone, was a model of simplicity of construction.
