Overview

Excerpt from Curves of Civil Engineering: The Transitman's Pocket Companion; Containing Instructions for Surveys to Locate the Center Line of Engineering Works, and Tables That Are Needed in the Field, in Connection With Circular, Transition, and Vertical Curves A new table of 1 Degrees Curve Functions is here given, in accordance with a new definition for Degree of Curve, which is found in the first paragraph of the text. With measurements on the curve the table is exact for all degrees. With measurements on chords, results are as close with this table as with similar published tables. So this table is prefectly applicable on work where the errors of chord measuring is considered negligible. Logarithms and tables of natural functions are not given because they should not be used in the field. Transit work is, or should now be, in trained hands, which are supplied with such tables as those published by Professor Jones, of Cornell University, by Von Vega, or by the U. S. Geo. Survey. Special problems, too, are considered as belonging in the classroom. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
