Explore the principles of macro-scale tribology and discuss the potential impact of tribology in enhancing sustainable development. Discuss physical properties of lubricants; lubricants and their composition; contact mechanics; hydrodynamic lubrication; hydrostatic lubrication; elastohydrodynamic lubrication; boundary lubrication; solid lubrication and surface treatments; wear of materials; nanotribolgy; and green tribology. Three lecture hours a week for one semester. Mechanical Engineering 378F and 379M (Topic: Enhanc Sustnblty Thru Tribolgy) may not both be counted. Prerequisite: Chemistry 301, Mechanical Engineering 302, Mechanical Engineering 334, Physics 303K, and Physics 103M with a grade of at least C- in each.
