PREREQUISITES:
AME 20212, AME 20241

TEXTBOOK:
Fundamentals of Machine Elements,Hamrock, B., Schmid, S. and Jacobson, B., 2 nd. Ed. McGraw-Hill Book Company, 2004.

COURSE OBJECTIVES:
This course is intended to introduce the mechanical engineering student to the basic components of machinery, and how to select and size these components to achievedesign goals in the construction of mechanical systems.

Topics:

• Introduction to machine design (1 class)
• Fracture Mechanics and Fatigue Failure (5 classes)
• Press and shrink fits (2 classes)
• Design of keyways and set screws (2 classes)
• Design of threaded fasteners and power screws (4 classes)
• Design of welded joints (3 classes)
• Helical tension and compression spring design (3 classes)
• h. Design of rolling element bearings (3 classes)
• Hydrodynamic lubrication, design of journal bearings (4 classes)
• Kinematic analysis of gear trains, planetary systems (3 classes)
• Selection of gears by AGMA and Lewis formulas (3 classes)
• Clutches and brakes (4 classes)
• Flexible machinery elements: wire rope, rubber belts, chains (3 classes)
• Examinations (2 classes)

Schedule:
This course meets 3 times a week for 50 minutes each meeting or twice a week for 75 minutes each meeting.

Contribution to Professional Component:
Engineering Science: 0 credits or 0%, Engineering Design: 3 credits or 100%

Contribution to Program Learning Outcomes and Assessment:

Computer usage:
1. A mathematical software package is useful for every homework, but not required for any homework.
2. Two projects, where mathematic programming is necessary for solution (dynamic journal bearing and fatigue failure of artificial hip).

Practice and Assessment Methods:
A large number of homework problems are assigned, graded and returned to the students. A recitation session is taught by the instructor where direct interaction with the students takes place. The examinations given during the semester are graded by the instructor and discussed with each student. The instructor wrote the textbook incorporating teaching tools such as tutorials and case studies contained on a compact disk where results can be quickly compiled.
