Sinopsis
Excerpt from Some Graphical Solutions of Electric Railway Problems
It should be noted that a different position of the point K will be located for each value of current, and in some cases it may be at too great a distance from the body of the diagram. To obviate this the relative positions of the speed-current and the volt-ampere dia grams may be changed, always keeping their current axes together.

Some Graphical Solutions of Electric Railway Problems (Classic Reprint)
Impresión bajo demandaLibrería: Forgotten Books, London, Reino Unido
Calificación del vendedor: 5 de 5 estrellas
Paperback. Condición: New. Print on Demand. This book presents a graphical method for solving electric railway problems involving the characteristics of motive power. The author, a professor of railway engineering, was dissatisfied with existing methods as they were not accurate or required too many assumptions to be made. The result was the development of graphical methods for determining proper points for cutting off power and applying brakes, motor performance with varying potential and resistance, starting resistance for series motors with rheostatic control, series-parallel control, and plotting speed-time and distance-time curves. The author gives detailed explanations of each of these methods with the use of clear and concise diagrams. These methods are accurate, practical, and do not require extensive calculations, so engineers will find it a practical and time-saving tool. 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. Nº de ref. del artículo: 9781333940522_0
