STRENGTH OF MATERIALS

Catalog description

Three credit-hours. Three hours of lecture per week. Analysis of stress and strain. Stress-strain relations. torsional and flexural loading. Bending moment and shear force diagrams. Bending stresses. Stress transformation. Combined Loading. Beam deflection and the application of superposition method. Elastic stability. There will be emphasis in the use of critical thinking when establishing the relationship of different loading conditions, the selection of pr oper dimensions, and the stress state of the mate rial. The entire course involves quantitative reasoning through the calculation of stress states, equivalent stresses, deflections, and stability conditions. Scientific reasoning will be necessary to apply the laws that relates elastic stress and their res pective deflections and to derive stresses from the fundamental principle of summation of forces distributed through internal areas of structural elements. ENGI 319 MATERIALS TESTING LABORATORY 1 CREDIT Standard physical tests of engineering materials including tension, bending, micro -hardness and macro -hardness. Basic metallurgy including grinding, polishing, etching and micro -structure identification. Heat treatment of steel including quenching and Jominy test. Students will develop the scientific reasoning, communication, and ethics and diversity skills required to study the properties of materials commonly employed in the industry, such as metal alloys, between others. ENGI 333 MACHINE SHOP LABORATORY 1 CREDIT One credit-hour. One three-hour laboratory per week. Operation of drills, milling machines, lathes, power saws, and surface grinders. Introduction to precision measuring techniques. Introduction to welding.
