Fundamentals of Machine Component Design – R. Juvinall, K. Marshek – 1st Edition


of Machine Component focuses on sound strategies and skills needed to navigate through large amounts of information.

Revisions in the text include coverage of Fatigue in addition to a continued concentration on the of component design. Several other new features include new objectives added at the beginning of all chapters; updated end-of-chapter problems, the elimination of weak and addition of new problems; updated applications for currency and relevance and new ones where appropriate; new system problems and examples; improved sections dealing with Fatigue; expanded coverage of failure theory; and updated references.
