Paperback. Etat : New. Print on Demand. This book provides an ordinary multiform compound curve of equal-length arcs, their degrees of curvature increasing in the order of natural numbers, arranged so that the seventh arc always coincides with the main circular curve. It presents several valuable features, including flexibility,… reduced reliance on tables, adaptability to curves of fixed offset or length, and intermediate transit points that can be set at any plus, saving time and trouble in spiraling old tracks. The book is easily grasped, memorized, and applied by transitmen with no previous knowledge of spirals, and the mathematical treatment is elementary throughout. On location, it is often not even necessary to run in the six-chord; a terminal curve of half the degree of the main curve and giving the same length as the spiral line can be substituted instead. This book is invaluable for any surveyor or engineer working on railroad design and maintenance. It is a comprehensive guide to the theory and practice of spiraling curves, and will be a valuable addition to any professional's library. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
