School Of Computer Science And Electronic Engineering
Module - Semester 1 & 2
Indicative content includes:
Mechanical Design Principles
- Understand the theory of material properties and failure and how this influences mechanical design choices
- Understand the theories of static strength, resilience, toughness and creep
- Understand the principles of design for static strength and how to apply these
- Understand the theory of fatigue failure including terminology, measurement, characteristic curves; Miner's Rule and S-N curves.
- Understand failure reliability of an assembly and the cost of reliability and the tools for exploring the failure of a design including fault trees, failure modes and effects analysis
- Understand and analyse engineering thermofluid systems, based on mass and energy conservation
- Design products for thermodynamics, fluid mechanics and turbomachinery applications
- Understand the principles of structural design, including; statics and dynamics, simply supported beam and torsion
- Understand the Ideal Gas Law and its applications.
- Understand the principles of heat and thermodynamics in chemical reactions
- Understand and apply basic thermodynamic concepts: thermodynamic systems, states, properties, work, heat, energy.
- Represent power generation and refrigeration cycles on T-S and P-H diagrams and determine the power generation or requirement for a given thermal duty.
- Describe the significance of Chemical Potential in mixtures.
- Use Standard heats and free energies of formation to evaluate equilibrium constants, and hence determine equilibrium concentrations in reacting mixtures at elevated temperatures and pressures.
- Understand deviation between ideal vs. real cycles
- Be able to apply basic thermodynamic relationships to real problems
- Carry out material and energy balance calculations separation processes by hand and using a computer package.
-threshold -Equivalent to 40%.Uses key areas of theory or knowledge to meet the Learning Outcomes of the module. Is able to formulate an appropriate solution to accurately solve tasks and questions. Can identify individual aspects, but lacks an awareness of links between them and the wider contexts. Outputs can be understood, but lack structure and/or coherence.
-good -Equivalent to the range 60%-69%.Is able to analyse a task or problem to decide which aspects of theory and knowledge to apply. Solutions are of a workable quality, demonstrating understanding of underlying principles. Major themes can be linked appropriately but may not be able to extend this to individual aspects. Outputs are readily understood, with an appropriate structure but may lack sophistication.
-excellent -Equivalent to the range 70%+.Assemble critically evaluated, relevent areas of knowledge and theory to constuct professional-level solutions to tasks and questions presented. Is able to cross-link themes and aspects to draw considered conclusions. Presents outputs in a cohesive, accurate, and efficient manner.
- Explain mechanical design principles and solve related problems.
- Explain thermodynamics and solve related problems.
