​Mechanical engineers are associated with the production and processing of energy and with providing the means of production, the tools of transportation, and the techniques of automation. The skill and knowledge base are extensive. Among the disciplinary bases are mechanics of solids and fluids, mass and momentum transport, manufacturing processes, and electrical and information theory. Mechanical engineering design involves all the disciplines of mechanical engineering. Therefore, this course aims to equip the mechanical engineering students with the fundamentals of these design activities and give them necessary skills to prepare complete, concise, and accurate calculation steps for machine elements. While the first part of the machine elements covering general stress analysis, failure conditions, shaft, spring, permanent and nonpermanent joints design, second part covers rolling contact and journal bearings, gears, clutches, flywheels, flexible machine element design and analysis tools. Also, in this course an introduction of vibratory systems, periodic motion, mass spring damper system, failures caused by vibrations will be covered.
