MAE 311 Machines and Mechanism I
Department course descriptions: Click Here.
EAS 209 and MAE 381. You should not take this course unless you have passed the prerequisites. A working knowledge of solid mechanics and stress analysis will be especially useful. Please see Prof. Soom if this is an issue for you.
Mechanical Engineering Design, Shigley and Mischke, McGraw-Hill, 5th Edition. This is a McGraw Hill Classic Edition. (The 6th edition is NOT SUITABLE) All or some of the following chapters will be covered. 1 Intro; 2 Stresses (some review and some new important); 3 Deflections (review); 5 Material properties (review); 6-7 Failure theories; 8-14 and16 Machine elements. Detailed book sections and topics will be noted as we proceed through the course. Some supplementary materials will be provided.
- Context of mechanical design
- Enable students to better understand why components fail.
- Introduce students to various machine components such as shafts, threaded connections, springs, gears, bearings, clutches, and brakes.
- Provide students an opportunity to design, size or select individual machine components using standard techniques
Upon completion of this course, the student will be able to:
- Develop hypotheses of failure associated with static loading.
- Incorporate fatigue as a criterion for dynamic failure in design.
- Design geometrical features of screws, bolts, and other fasteners.
- Analyze stresses and deflections of helical springs and design springs for given loading.
- Identify appropriate bearings for a specific design application.
- Perform force analysis of spur gearing and design gears for size and performance
- design brakes and clutches
|Two tests||20-25% each|
|One/two possible mini-projects||0–10%|
Approximate cut offs for final grades are A/B 85, B/C 70, C/D 55, and D/F 45. If you receive an 'A' or A- on the final exam, you will be receive at least a B or B- in the course, regardless of overall numerical average. However all parts of the course must be completed. Any disagreement pertaining to test or exam grades must be addressed, in writing, to Professor Soom within a week of the return of the graded item. Homework issues are to be first addressed with the TAs.
Students may work on homework individually or in small groups no larger than three people total. A single assignment may be turned in for groups, with each person’s name clearly written on the upper right hand corner. Homework MUST BE turned in during class on the date due or the student will receive no credit.
Tests will take place during the regularly scheduled class period. The Final Exam will take place during Finals Week at the officially scheduled time. Use of supporting materials will be announced prior to any test or exam. (For the tests, it is most likely that one 8 1/2 by 11 inch sheet of formulae will be allowed. The final exam will mostly likely be open book.) Make-up exams will only for medical reasons or other provable extreme situation. If a test or exam will be missed, the student should contact the instructor at the earliest possible time.
