This handbook has been written for working designers, and its place is on the
designer's desk—not on the bookshelf. It contains a great many formulas, tables,
charts, and graphs, many in condensed form. These are intended to give quick
answers to the many questions that seem constantly to arise.
The introduction of new materials, new processes, and new analytical tools and
approaches changes the way we design machines. Higher speeds, greater efficiencies,
compactness, and safer, lighter-weight, and predictably reliable machines can result
if designers keep themselves up to date on technological changes. This book presents
machine design as it is practiced today; it is intended to keep the user in touch with
the latest aspects of design.
