EGR 254 : Mechanics of Materials and Structures
In this capstone course, the concepts of stress and strain caused by tensile, compression, shear and bending forces and the associated material behavior are studied. Classical and computer methods are used to analyze beams, trusses, and structures. Students also study centroids, centers of gravity, moments of inertia, torsion, column action and the strength of bolted and welded joints. The design of structural members made of wood, steel, and reinforced concrete is introduced. In the laboratory, students perform testing techniques used to analyze the mechanical properties of materials and evaluate structures. Prerequisite: EGR 251. Three lecture hours and three laboratory hours per week. Instructional Support Fee applies.
Course Outcomes
Upon successful completion of this course, students will be able to:
1. Define thermodynamics concepts including: pressure, temperature, work, heat, energy and how they apply to open (flow) and closed (non-flow) systems.
2. Define energy conversion, enthalpy and specific heat and apply them using the Energy Equation.
3. Calculate efficiency and entropy and apply them to reversible and irreversible cycles, specifically The Carnot Cycle.
4. Illustrate the concepts of phase, phase change (vaporization), quality and enthalpy and use them to determine the properties of steam using computer programs, the Steam tables and Mollier chart.
5. Analyze Carnot, Rankine and actual power generation cycles and alternative energy sources using graphical and mathematical techniques.
6. Apply the concepts of specific heat, gas constants and partial pressure to a variety of processes using ideal gas law, the gas tables and the psychometric chart.
7. Analyze the Otto, diesel and Brayton cycles and the internal combustion engine using graphical and mathematical techniques.
8. Calculate coefficient of performance and use refrigerant tables to analyze refrigeration cycles.
