The authors of this classic work have declared several purposes but the main and major was to provide all interested readers, and particularly students/teachers with enough comprehensive and practically useful compilation of different progressive problems which commonly embody the fundamental principles and also the real examples directly related to the practical mechanical drawing. All of those problems have been offered in the form of some specification sheets and, in addition to that, a lay-out sheet from which the students are supposed to build the completed drawing. The referenced specification sheets, in turn, are providing a statement of the problem; they are, in most cases, supplemented with some text matter that bear upon and emphasize the things to be taught in the problems, or providing some relevant technical information. The proper utilization of the proposed specifications plus the reference sheets is expected to facilitate the moving towards the creation of the necessary level of self-reliance and the personal efforts of the students. All of the problems chosen for inclusion into this publication have been fully supplemented and such approach has made the content of this volume very flexible. The reference sheets contained in the book are made use throughout all docs and will definitely be among the valuable features of this title.
