A First Course in Nomography by S. Brodetsky

From the PREFACE.

In many branches of science, in engineering practice, in technology, in industry and in military science, Nomography is a recognised means of carrying out graphical calculations. The ballistic constant in gunnery, flame temperature in the research of coal-gas combustion, the angle of twist in a thread of given thickness with a given number of turns per inch, the conversion of counts in the textile industry, can all be calculated by means of nomograms. Nomographic charts are simple and certain in use, so that calculations formerly entrusted to skilled and responsible computers can now be safely left to the care of a comparatively unskilled subordinate. It is the object of this First Course to offer a clear and elementary account of the construction and use of such charts.

The method of treatment chosen is based on experience gained in the making of nomograms for various technological departments in the University of Leeds, and in other ways. It is a treatment that should be found useful by the reader who desires to become acquainted both with the theory of nomography and with its practical use. Chapter III begins the nomography proper, but the reader is advised to study Chapters I and II first, in order to see how the nomograms in Chapter III can be constructed. Special attention is directed to §§ 49-50 in Ch. IV, and to Chapter VIII. Answers have been purposely omitted, even where the examples lead to numerical results.

The sincere thanks of the author are due to Prof. W. P. Milne, M.A., D. Sc, Mr. R. C. Fawdry, M.A., and Mr. A. W. Siddons, M.A., for their kind help in reading the manuscript and making many suggestions, most of which have been adopted. Thanks are also due to Mr. R. M. Milne, M.A., for suggesting an important example in gunnery, and to the Editor of the Mathematical Gazette for permission to make use of the subject matter and diagrams of an article by the author published in that journal. Extensive use has been made of d'Ocagne's Traite de Nomographie, and the author's great indebtedness to this admirable work is gladly acknowledged....
