Machine design is a large subset of study under mechanical engineering design which includes design of common components used in machines.
This is a mega-course of 3 courses in 1 which covers multiple aspects of design of Shafts and elements which are generally mounted it - Bearings and Gears.
It is a deep dive into the Shaft design process and selection also deals with the Bearing selection in detail . Then moving to a deep dive in Gear design with practical CADdesign of gears based on input specifications.
