Mechanical Engineering

Introduces the technology of 3D parametric geometric modeling to design and model mechanical engineering parts, assemblies and devices. Geometric variables and their interrelationships will be covered by projects involving the design of mechanical components, assemblies and machines to meet functional requirements. Manufacturing requirements including Geometric Dimensioning and Tolerancing. The use of the model for analysis, optimization and simulation will be stressed. Presentation of the model through engineering drawings and pictorial renderings. Animation of mechanisms. A comprehensive commercial CAD program will be used. 

Analysis of the strength of a mechanical device. Shapes and materials will be modified to meet deflection and stress limits. Written reports will document choices made and assessment of design. Group oral reports. 

Fundamental concepts of linkages, displacement, velocity and acceleration analysis using graphical and analytical methods. Static and dynamic force analysis of linkages. Design of cams, gears, and gear trains including ordinary and planetary gear trains. Balancing rotating masses. Simple gyroscopic effects.

Optimization of any design is essential either to remain competitive or to improve product efficiency and quality. Several optimization methods are presented through a variety of mechanical design and industrial engineering problems. Topics include: single and multi-variable unconstrained optimization, linear programming, transportation, assignment and network problems. Other topics such as constrained and global optimization are introduced.

Properties of a pure substance - work and heat. First law and applications in non-flow and flow processes. Second law and reversibility; entropy, applications of the second law to non-flow and flow processes. Analysis of thermodynamic cycles. Otto and Diesel cycles. Thermodynamic relationships. 

Laboratory experiments and measurements related to Fluid Mechanics I. Laboratory reports and readings are assigned.
