Excerpt from Mechanical Drawing Problems This volume is a book of examples and problems for the study of mechanical drawing. It is intended to be used under the direction of a teacher, although the ambitious and painstaking student can solve many of the problems without such aid. It aims to provide a large selection of typical drawings carefully worked out as examples, each one of which is accompanied by appropriate problems suitable for elementary and advanced work in mechanical drawing. Explanations and directions are, when needed, expressed in simple and direct language, and in the fewest possible words. The principles of the construction of a drawing are shown in the examples in the graphic language of the draftsman. The book is divided into three parts. The First Part gives in brief outline such matter as the student will need to know before beginning work. It contains, also, a limited number of geometrical constructions which will be found helpful in solving some of the problems given. The Second Part - the practical work - is divided into four sections, namely: Projections, Developments and Intersections, Isometric Drawings, and Machine Details. Nearly all the example-drawings are fully dimensioned and, where necessary, described by explanatory notes. They are not to be copied but are intended to serve as a guide to the student when making his own drawings for which directions are given in the form of problems. In each section there are many more problems than any one student can work in the amount of time which is usually allotted to the subject of mechanical drawing, and a judicious selection must necessarily be made by the teacher to meet the individual students requirement. These problems are arranged in the order of their difficulty. The problems given in the beginning of each section are not too difficult for a beginner in mechanical drawing, while those toward the end of the sections will be found suitable for advanced students. Each section begins with problems that are suitable for Junior High Schools, High Schools, and Evening Schools, and advances gradually to problems that are more difficult of solution, suitable for Vocational Schools, Trade Schools, and Colleges.

Excerpt from Problems in Mechanical Drawing The teacher will find it convenient to have a model of each of the forms represented in the first two or three groups for use in giving individual instruction to students who fail to understand the problems as given, though with rare exceptions the small sketch in the right-hand upper corner of the sheet will serve as a good substitute for the model.

Excerpt from Practical Problems in Mechanical Drawing and Blue-Print Reading Much criticism has been directed at the copy method of teaching Mechanical Drawing and undoubtedly some pupils have copied drawings which they did not clearly understand. The attempt, however, to make a problem of every drawing has been' responsible for much poor teaching. Many boys have gained the impression that a third view was always necessary, when as a matter of fact, two views of an object gave all of the information necessary and the drawing of the third view was.a waste of time. Similarly if dotted lines on a view give the pupil a clear idea of an object, the drawing 'of a section is poor practice. It is suggested that the test drawing, the side view or section or sketch be made on a sep arate sheet in pencil, thus saving time and avoiding the possibility of the pupils receiving the impression that it must be made to complete the drawing.

Excerpt from The Practice of Mechanical Drawing for Self-Instruction A draftsman should be familiar with the problems in this chapter, and should be able to construct them very accurately when necessary. In practice, they are seldom used; but unless he knows how to draw them with precision, he will not be apt to get them so nearly correct when drawing them approximately. Problems of this kind are about the best exercises for beginners in mechanical drawing. The desired results will not be obtained unless extremely 'fine, hair-like lines are drawn, and all centres and other points taken exactly on these lines. Therefore it is important to use very hard pencils sharpened to a needle or chisel point, and to avoid making holes in the paper with the compasses. Given and required lines should be drawn fine in ink, and construction lines drawn in pencil only; but, to distinguish them in these problems, given lines are heavy; required lines fine; and construction lines broken.

Excerpt from The Fundamentals of Mechanical Drawing While no course is outlined for the teacher, several hundred carefully chosen drill problems in the elements are provided. The orthographic and isometric problems may well be supplemented by the use of a varied assortment of wooden blocks, some of them similar to those illustrated on Plates 20 and 21, others far simpler in outline. From these blocks the student should make ortho graphic and isometric drawings, some of which should be dimensioned.
