Paperback. Etat : New. Print on Demand. This book is a significant contribution to the field of electric street car operation, a topic that has historically been overlooked in favor of steam railroads. The author, an expert in civil engineering, recognized the increasing importance of electric lines in handling not only passenger but also freight traffic. This book presents the development of a method and apparatus for accurately measuring train resistance, a crucial factor in determining ruling and maximum grades for electric railway construction. The author discusses the limitations of existing methods, such as dynamometer cars, and explains how their inaccuracies stem from the difficulty in determining velocity, especially when the velocity is not constant. This book comprehensively explores the concept of using a "drop test" or "drifting test" to derive train resistance from the velocity required for cars to descend a known grade. The author meticulously details the theory behind this method and provides a practical guide to its implementation, including the construction of apparatus that can withstand the impact of car wheels at high velocities while remaining sensitive enough to respond instantly and not impede the car's progress. Ultimately, this book's insights on rolling resistance offer valuable guidance for the efficient construction and revision of electric railway lines, contributing to the safe and economical operation of this increasingly important mode of transportation. 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 r�f. du vendeur 9780282753016_0
