Applies the principles of mechanics and mechanics of materials to machine design. Analyzes the elements of machines in terms of their static and dynamic behavior. Discusses selection and sizing of machine elements. The finite element technique for the analysis of machines and their counterparts may be used.

Assessment and Requirements
1) Cognitive skills will be assessed by the instructor as homework problem sets submitted by each student are read.
2) Finite element analysis tool embedded in CAD software can be used for design of machine elements.
3) Term project for design of machine elements can be used for integration of computer aided, drafting, and machine design.
4) Problem solving and critical thinking can be evaluated through mid-term and final exams.
As per decision of department.
Credit for Prior College-Level Learning
Suggestion: Successful candidate has/had worked in design department of any industry. Instructor can examine skills of candidate through a short project for sizing of machine elements and finite element analysis. After successful completion of project, instructor may grant Credit for Prior College-Level Learning.
