An excerpt from the beginning of the INTRODUCTION: 1. Object of Nomography. We are all familiar with graph-drawing as a means of solving equations. But ordinary graphical methods are often inconvenient, because a separate graph is required for practically each equation we have to solve. Thus, to solve the quadratic equation x2+x-2=0we need to draw the graph y=x2+x and find where it is cut by the line y=2. To solve the equation x2+2x-2=0, we must draw the graph y=x2+2x and similarly for other values of the coefficient of x. The object of Nomography is to enable us to solve all equations of a given type by means of one diagram. Thus all quadratic equations of the type x2+ax+b=0 can be solved by means of one graph which can be drawn once for all. In the same way all cubic equations of, say, the form x3+ax+b=0 can be solved graphically by means of one diagram. Such a diagram is called a Nomogram. It is also the object of Nomography to enable us to find the value of a complicated expression graphically. Let us consider, e.g. , the formula for the pressure R in pounds on a flat plate normal to a passing current of air, viz, R=0.0194W*SV2 (lbs.),where W is the weight of the air in pounds per cubic foot, S is the area of the plate in square feet, and V is the relative velocity of the air in feet per second. If the pressure has to be found for a number of different plates at various velocities, it is obviously convenient to have a diagram which, having been constructed once for all, can be used for any values of W, S, and V that are likely to occur. In the present volume we shall consider in a simple manner how to construct and use nomograms for multiplication and division in formulae like the one for air pressure, as well as the more general metho.

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 be.
