Description

This course first briefly discusses materials strength and deformation, fracture toughness, and stress intensity factor to build the corner stones for any machine design work. It then focuses on the design of five basic machine parts: fasteners, springs, bearings, gears and shafts. The primary subjects in this course are thread standards and definitions, the mechanics of power screws, threaded fasteners, analyses and design of springs, fatigue loading, bearing types, bearing life, bearing load, selection of bearings, thin film lubrication, hydrodynamic theory of lubrication, gear conjugate action, contact and interference of gears, shaft design and analyses.
