MECTK222 — Machine Design II
3.0 HR. (OC) Prerequisite: MECTK 221 with a grade of C or better, credit or concurrent enrollment in MECTK 204, credit or concurrent enrollment in PHYS 113, and MATH 130 with a grade of C or better. This course is a continuation of MECTK 204 in that it involves more complicated statics problems and stress calculations. The concept of principal stress is further developed. Principal stress directions are used to gain an insight into component failure analysis. The topic of fatigue design and theories of failure are introduced. The above concepts of stress analysis are applied to springs, drive shafts, gears, bearings, bolts, and welds. A realistic design project is carried out in the laboratory with emphasis on project management. Two lecture and three laboratory hours per week.
