Weick Charles W. Elementary mechanical drawing; theory and practice

First Edition Second Ipression. — New York: McGraw-Hill Book Company, 1915. — 250 p.This work aims to provide an elementary text-book for class use on the modern conventions, theory, and practice of mechanical drawing. In scope and purpose it is designed to offer a basic treatment of the subject. Beginning with the elements it develops instruction in regular progress till it covers the fundamental training needed for general practice in the drafting office. Its object is to cover both theory and practice. The treatment of theory in the text is as brief as clearness permits, but it is expressed with all necessary fulness and elaboration by the aid of many illustrations in which the theory is implicit. The conventions of the drawing-room are duly explained. Emphasis, however, and enforce the theory at every stage of the instruction. The fundamentals necessary for the intelligent study and prosecution of a course in mechanical drawing are contained in the Chapters I-VI, preceding the examples and problems. These chapters when used are best taken up in connection with the course in practice as it develops. The chapter on geometrical drawing contains many principles useful to the draftsman in practice. The student should review this chapter from time to time till he is familiar with these principles and can avail himself of their aid in the execution of appropriate problems in the course in drawing. The chapter on mensuration affords helpful material of instruction for such classes in mechanical drawing as include mensuration in the work of their course.
