Engineering Graphics

No matter how far reaching the research of scientists or engineers extends in developing new ideas and concepts, nothing can be built or manufactured without drawings. Completely revised and updated, Engineering Graphics, Second Edition explains the principles and construction of engineering drawing in a clear, concise, and straightforward style. This allows students from different areas of engineering to understand engineering drawings with minimum effort. The book gives students a complete understanding of technical drawing - the basic working tool all engineers must use.

See what's new in the Second Edition:
§ Chapter on Intersection of Surfaces
§ More than 200 exercises
§ 100 solved problems
§ Over 300 illustrations with detailed step-by-step constructional procedure
