Catalog
Description: Prerequisites: Elementary strength of
materials, calculus (AAS level), Physics I, C++ or BASIC. The principles of
strength of materials are applied to mechanical design. Topics include theory
of failure, stress concentration factors and fatigue, the design and analysis
of shafts subjected to static and dynamic loadings, and critical speed of a
rotating shaft.
Textbook: Spotts,
Shoup & Hornberger: Design of Machine Elements, Prentice-Hall, 8th edition.
ISBN 0-13-048989-1
Reference materials: Summary
of topics and formulae – you can print it out for your easy reference
Strength of
Material online course from University of Wisconsin - helpful in reviewing
elementary concepts
