Machine Design
ME 45310/ 3 Cr.
This course prepares the student to: apply basic mechanics (statics and dynamics), mechanics of materials, and probably and statistics to the analysis and design of machines and machine components; design for strength of various machine components; study of stress/strain and force/deflection relations in machine components; understand fundamental approaches to stress and fatigue analysis and failure prevention; incorporate design methods for machine components such as shafts, bearings, springs, gears, clutches, breaks, chains, belts, and bolted and welded joints; and solve open-ended machine design problems involving structural analysis, life prediction, cost, reliability analysis, and technical communication.
