Excerpt from Mechanism
The subject-matter of this book treats of pure mechanism, or the kinematics of machines. It is intended for use in the University and Technical Colleges, and is not meant to be a philosophical treatise on the subject; we have the works of Willis, Rankine, and Beuleaux for that. It is the outcome of experience gained in lecturing on the subject at the Universities of Cambridge and Liverpool, and at the Royal Naval College, Greenwich. The logical treatment of the subject admittedly presents great difficulties, and it was only after anxious thought that the present arrangement was adopted as being, in the authors opinion, the most suitable for the average student.
It was thought desirable to insert an elementary descriptive chapter, which includes an account of various machine tools, and of mechanisms required for special purposes. As far as possible, those illustrations have been selected which, in the writer's opinion, are of most general interest. The remaining chapters include a full discussion of straight-line motions, indicator mechanisms, quick-return motions, couplings, velocity diagrams, approximate solutions to link motions and radial valve gears, acceleration diagrams, toothed wheels, non-circular wheels, cams, and machines for cutting teeth; and a number of numerical examples are added at the end of the book.

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

Paperback. Etat : New. Print on Demand. This book is an illustrative introduction to the object, design, and principles that underlie mechanical machines. It is a foundational book for engineering students and those tasked with designing mechanical parts. The author draws upon their own lectures provided at universities and the Royal Naval College, Greenwich to provide a logical yet accessible treatment of the subject. They begin with simple machines, moving on to kinematics and the graphical representation of velocity and acceleration within mechanisms, discussing toothed wheels and non-circular wheels, cams, and machines for cutting teeth along the way. The author interjects numerous numerical examples to aid the reader in applying the concepts discussed. This book will give readers the tools to investigate the forces that mechanical parts will experience, and thus design parts that will withstand those forces. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781332022151_0
