Produktbeschreibung
Excerpt from Mechanical Drawing: A Manual for Teachers and Students The following notes are intended for students, and for teachers of elementary work, particularly for public school teachers. There are many books on the subjects of projection and working drawings, but none which present the principles in ways suited to the needs of the large number of teachers who are required to give instruction in these subjects in the public schools. Most of these teachers have had little instruction in the subjects and frequently do not understand problems which they arc expected to explain. This occurs because too difficult work is often planned for their grades, and also because the instruction which many public school teachers have received has been so advanced and theoretical that the simple principles which alone are necessary for elementary work have been lost in the attempt to understand descriptive geometry and the drawings of machine and other details, whose nature and use are often not known. To understand descriptive geometry certain qualities of mind are absolutely necessary, and many find it impossible to comprehend even the simpler problems of this subject. The draughtsman or drawing teacher of advanced work who is without practical knowledge of the subject of descriptive geometry is very poorly equipped for his duties; but this knowledge is not necessary for the public school teacher, who will find it best to treat the subject of working drawings in a much simpler way. This book presents principles and not a graded course of lessons. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
