MEC723: Mechanical Systems Design

This is the home page for design-related materials by Dr. Salustri for MEC723.
You should bookmark https://deseng.ryerson.ca/mec723 for easier access.

Announcements and other information will be made available through D2L.

I do not carry such information in my mind since it is readily available in books. The value of a college education is not the learning of many facts but the training of the mind to think.Albert Einstein, 1879-1955

Education is what survives when what has been learnt has been forgotten.B.F. Skinner, 1904-1990

Lecture Material

Most lecture material is based on the design part of my wiki. Where there are no slides, one can expect a review of the relevant materials as indicated in the Weekly Schedule.

During in-class workshops (as of Week 3), students will be expected to take notes collaboratively in shared Google Docs. Links to individual documents are listed below. The Google Docs for student notes are all in the shared folder In-Class Workshop Student Notes.

Slack can be a great tool to help coordinate projects. This is an anonymized dump of an entire semester of Slack for a MEC723 project involving the whole class. It's interesting to consider how communications happened and what the major topics of conversation were.

What students have said

Below are comments from actual students about this course, drawn from comments submitted with the Faculty Course Survey some time since I arrived at Ryerson in 1999. I have provided commentary as required.

Student comments are verbatim as provided by the students, in boxes; instructor remarks are in plain text below each box.

Although the lab and project marks can be quite strict, you respect the reason why this professor and his TA teach to such a high degree of detail and correct ideation. He understands that a spoken thought can have multiple interpretations, and goes out of his way to convey a concise concept when explaining in lecture. People often forget that students are people too, and although it was a small class size, he really took the time to care about how much his students are learning from this course. That speaks a lot about this man's character. He is a knowledgeable individual, a hard marker, but you will be forced to contort your mind into many useful ways with this course and this professor. He beckons you to think creatively and to do tasks with efficiency and purpose. Perhaps the best professor I have had the privilege to learn from. I wish there were more professors like this gentleman.

Fig. 1: Why, thank you. Thank you very much.

Good course, but working hard for the assignments and the Urban cycle wasn't paying off. Group got demoralized since hard, creative and thoughtful work was being given crap grades. I guess its cuz the course is design oriented and its easy for the TA to pick on irrelevant faults and interpret the contents erroneously as desired and given penalties as desired no matter how well you explain your work. This causes us to loose [sic] motivation, dedication and enthusiasm for a course that is supposed to be our pre-capstone course. Other than that, I do like how the course teaches us step-by-step methods to address design problems. Better evaluation of the assignments would greatly help. I would rate this course 7 or 7.5 out of 10.

Let's be clear, the TA follows my lead. Sometimes mistakes happen, and they get corrected eventually; but the idea that the TA is grading things differently than the instructor would have is wrong. Nuance and interpretation are often the aspects that make or break a design. No one else tries to explain the importance of nuance and interpretation of language in engineering, but that doesn't mean it can be ignored. By going after such features of student work, we're making you aware of how the real world will treat your work. We haven't the time to address all of these shortcomings in your education, but I'll be damned if I don't at least show students the kinds of problem that can arise.

Better class scheduling times if possible.

Scheduling in this course is always a problem. Every year, the calendar changes, and the timetable changes. This means that every year, there's some new problem that screws something up. We usually do not get our timetables till late August, so we have almost no time to adjust the course to account for those timetabling “oddities.” And it's different every year. We are trying to find a more permanent solution, but we just haven't been able to come up with anything that reliably works every year, no matter what timetabling does.

Overall a great experience so far. Couple things could be done differently. The simultaneous urban cycle and main design project splits students focus and I feel is detrimental to them both. The urban cycle is completed in mec325 so it seems unnecessary to redo it. I think it would be more conducive to do small case studies and put an even larger emphasis on the main project removing the urban cycle. As it stands now, many students will delay working on the main project to complete urban cycle milestones. It is not that work is overwhelming, it is more that the split focus denies either project the students full attention.

Excellent point. MEC723 and MEC325 are rather tightly coupled. The introduction of the urban cycle in MEC325 is relatively new. The key from my point of view is to be confident that as MEC325 changes, MEC723 doesn't suffer - and vice versa. Conservatively, it makes sense to keep the urban cycle in both courses till a really good alternative is developed. Every year, both courses get tweaked. I hope that within a couple of years, we'll be in a position to do some major adjustments to both courses. Getting rid of the urban cycle from either MEC325 or MEC723 is a priority, but there's other issues to be dealt with too. Rest assured, however, that we know about this problem and are actively pursuing alternatives.
Getting comments like this is very useful, because input from students is a great way to increase pressure on the administration to let us change the course content significantly.

Should definately by a year long course. Perhaps “field trips” would help engage students deeply. The size of the class, 15 students, is ideal for a design class.

I wish I could make MEC723 a year long course, but that would effectively add a course to the curriculum, and that is, as things stand today, an administrative “no-no.”
Field trips are possible, but they're a royal pain to arrange - I would have to do all the legwork myself because there's no infrastructure to assist me on these kinds of things. I will certainly take this under advisement and see what can be done in future years.
