course provides students with the opportunity to develop and demonstrate an understanding of the basic procedures used in the analysis and design of mechanical systems based on both factor of safety and reliability criteria Topics covered include stress de ection and stiffness analyses statistical and reliability considerations material behavior and manufacturing process requirements static and variable loading conditions and nite element analysis using commercially available software and CSS hardware Students are expected to acquire and exhibit the ability to apply this material and methodology in making rational design decisions for elements of typical practical mechanical systems Course Objectives ABET Criteria Students will have an understanding of the concept of stress and
