Through illustrations, tables, and straightforward calculations this book shows how to design improved and less expensive machine, structural, and architectural parts. Offers a wealth of design techniques usually gained only through extensive experience. Explains how to synthesize forms of parts so as to reduce weight and maximize strength, and reveals concepts and principles, in an easy-to-follow manner, which can be used by the designer in the initial phases of design without having to use design analysis. Chapters cover free body diagrams, force flow concepts, efficient and inefficient stress patterns, form design (including the tetrahedron-triangle principle, the uniform shear or hollow shaft principle, the mating surface principle, and the load lever principle), tension, compression and bending, torsion, contact stress, resistance to buckling and impact loading, joints, and structural efficiency. Seven appendixes provide information on physical constants of materials, SI prefixes, units and symbols, conversion factors, properties of sections, and bending diagrams and formulas.
