Excerpt from Applied Mechanical Drawing for First and Second Year Classes in High Schools: Technical, Trade and Vocational Courses, and Evening Schools In planning this course in Applied Mechanical Drawing for pupils in the first and second years of high school, the main purpose has been to establish, wherever possible, a close relation between mechanical drawing, mathematics and shopwork, omitting the usual abstract problems which have no direct application to either subject. Almost without exception, each problem demands some mathematical calculation before the pupil can proceed with the drawing. Our experience leads us to believe that it is the better plan to present a minimum amount of explanatory text in connection with a completed drawing of a typical problem coming under each topic in the course. This enables the pupil to readily comprehend and easily understand the requirements of the ensuing problems which are given in text form. Wherever necessary these problems are accompanied by freehand perspective sketches suggesting the object which is to be represented by the mechanical drawing. The problems in design for shop drawings of wood-turning and simple pieces of furniture offer an excellent opportunity to relate constructive design in the drawing room to the practical work of the shop courses. In this connection it has been found more practical and productive of better results to present a number of suggestive outlines which aid the pupil to design and draw the particular piece that he plans to construct in the shops. Facility in design ought not to be considered the chief aim in working out these problems. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
