Mechanical Engineering Principles and Technology

Course details

This course introduces the basics and fundamental concepts and applications of mechanical engineering. The course includes an introduction to the basic principles of mechanical drawings such as tolerances, symbols, sections, fasteners etc. The use of computer aided design and good drawing office practises are also discussed. The properties and mechanical behaviour of engineering components are presented, along with stress and strain, fatigue, fracture, creep and corrosion. Mechanical design philosophies are discussed with the focus on the use of safety factors during the design for static strength. Students will have the opportunity to gain some insight in the process of mechanical design for manufacturing/production.

Various manufacturing operations will be presented, starting with the production of metal and alloys. The methods to shape metal into its final desired shape, such as casting, forming, machining, welding etc. will be discussed. Students will be introduced to the use of computerised methods of manufacturing (CNC, CAM) and also the use of rapid prototyping. Principles of mechanical automation as it is typically found in industry will be discussed with the focus on the application of hydraulic and pneumatic systems. There is also a discussion on electric motors, mechanical actuation systems and common control systems (e.g. PLCs).

The course will also introduce the various aspects of pipe technology, including types of pumps, flanges, gaskets, jointing methods, pipe support and standards. The basic design and analysis of pipe systems will also be presented. An introduction of underlying practical principals of thermodynamics will also be included.

The course closes off with a presentation on one of the most important aspects in mechanical engineering, namely maintenance. A discussion on the various types of maintenance philosophies and their underlying principles will enable students to identify the correct maintenance approach for their workplace.
