Paper Description

Edit Paper Description Content

This paper applies the fundamentals theory taught in ENGEN110, ENGEN111 and ENGEN180 to understand the operational principles of electromechanical machines and power transmission mechanisms. Problem-based learning is used in conjunction with experimentation to compare theory to real machine behaviors. This paper covers analysis of machine systems and selection of power sources and matching transmission components. Important power transmission components are covered including gearboxes, gears, chains, belts, couplings, shafts, clutches, brakes, bearings and pneumatics.

Paper Structure

Edit Paper Structure Content

Students attend 2 one hour lectures and a 2 hour laboratory/problem solving session each week. The lecture slots may be used as problem solving session depending on the topic being discussed. This paper emphasizes practical application of the theoretical knowledge through experimentation and problem solving during the laboratory session.
