[All Rights Reserved.] އ PREFACE TO THE FIRST EDITION. > THIS book is intended for the use of Engineering students in schools and colleges, and as a text-book for examinations in which a knowledge of Practical Geometry and Machine Drawing is required. The chief reason which has led to its preparation is that during the time I was engaged in teaching on the Engineering side of Dulwich College, and had charge of the classes in Geometrical and Mechanical Drawing, I found it impossible to obtain a book wherein the problems, or examples, were not accompanied by diagrams which the student could easily copy, without in the least knowing to what they referred. In Plane and Solid Geometry there was a lack of properly graduated questions, and such important parts of the subject as problems on loci, the construction of the useful plane curves and their practical application to cams and wheel-teeth, the interpenetration and development of simple solids, and isometric projection were only to be found in advanced books-although really more suited for elementary students than the troublesome problems on 140101 |
