Ran in 4 of the last 7 terms. Winter 2027: not on the schedule. Spring 2027: schedule not out yet.

A continuation of the ME 322 course in analysis and synthesis of machinery, including advanced analysis of machine elements such as clutches, brakes, couplings, journal bearings, and gears. Advanced machine design concepts such as reliability, optimization, and techniques for stimulating innovative design. A synthesis project involving the machine elements studied is usually included.

  • I like the course content but 40% of the course grade depended on an absolutely absurd design project which took up more time in the term than our FYDP. You could easily learn the material of this course by just reading Shigley. Absurd amount of work vs. benefit to the student

  • Message to all mechs looking to take this course: DON'T DO IT IF YOU WANT TO HAVE A FUN TERM. The project is way too large, to the point that it was taking away time from my capstone project. There are 3 progress reports and a final report. On top of that there are 2 quizzes worth 15% each. No final exam, but don't let that fool you.
    The project relies heavily on doing your own research and whatever knowledge you retained from MODS and Mech Design 1. They basically throw a ton of information at you all at once and tell you to figure out the rest. The feedback we received on the progress reports was minimal and irrelevant.
    In a way, the course makes you a better engineering because it forces…

  • Martine McGregor was the course instructor when I took this course. She posts all the notes which is nice but you don't really have to go to lectures as she basically summarizes the shigley's textbook. This course definitely took up the most time and effort during 4A since there are 4 reports and each of them requires significant work. The project itself is not very interesting and very tedious since you're tasked with designing a mechanical press. Our final report was 85+ pages, and the TA did not give any feedback. The TA for this course also expected us to go into so much detail because I'm pretty sure he did not understand what was going on. This course provides little new information…

  • Taught by Martine McGregor, her first time teaching. Course has a HEAVY project centered around the design of a mechanical punching press. 4 design reports, each one is 70-100 pages. The project will make you and your group tear your hair out, so be warned. Martine is very kind, helpful, and laid back though, would definitely have her again. She said she is going to rework the project, so that might be good. 2 quizzes that were fully open book were the other assesments-no final. The course material isn't that helpful-brakes, clutches, bearing selection, gear design. Only take this class if you are sure you can make a good group and that you won't be stuck doing the project work yourself.

  • Very very very easy course and quizzes. The project was ABYMSALLY long. Start early on it or you're literally screwed for the rest of the term.
