Book Description

Excerpt from Descriptive Geometry: A Treatise From a Mathematical Standpoint, Together With a Collection of Exercises and Practical Applications Descriptive geometry is essentially a mathematical subject. The application of its principles to the making of working drawings, however, and the modifications which are made to suit the contingencies of practice, have had a tendency to obscure this fact, and like other theoretical subjects it has suffered mutilation in the interest of short cuts to immediate practical uses. But does not technical education, after all, consist chiefly in an equipment of sound theory? It has been the author's purpose to refrain from any attempt to hold the student's interest by clothing a few principles with some immediate pratical application, but instead, to present a sound theoretical treatment. How well he has succeeded he leaves others to judge. The principles are herein formulated under theorems, as in plane and solid geometry; illustrative problems are solved in accordance with these theorems and special constructions discussed. The plan of; at least, one well know text is followed of dividing all problems into two parts; the first of which is a statement of the geometrical principles and the theoretical solution called an analysis; the second is a description of the graphic solution, accompanied by a drawing. An important feature is added, however, of giving the statement of the geometrical conditions and the solution in the analysis in a general form, instead of being made to refer to a certain kind of problem exclusively.
