Amazon.com description: Product Description: This Second Edition, revised and updated, retains the features of the first edition and incorporates several improvements that stress and promote precise thought in the solution of mechanical component design problems. The major change is the addition of the sample problem format, which includes a restatement, solution and comments for the problem with respect to: given, find, schematic, decisions, assumptions, analysis and comments. A decisions format has also been added which allows students to clearly see the differences between design and analysis. Further changes include: a more in-depth and unified treatment of the basics of work, energy and power and their relationship to the thermodynamic approach; a more direct presentation of the systems of units and dimensions; and additional homework problems without repetition of problems.
