ME 4730/5730, Fall 2014
Course schedule and assignments are here.
Homework policy: To get credit, please do these things on each homework.
a) Hand in in at the start of class on Wednesdays. Unless stated otherwise, homework is due on the first Wednesday that gives you 6 or more days to work on the HW. That is, homework associated with a M, W, or F lecture is due, 9,7 or 12 days later, respectively. Late (1 minute or 2 months) homeworkwill be accepted for reduced credit. More late more reduction. Contact your grader (course page).
b) On the first page of your homework, please put the following to ease sorting:
On the top left corner
Please put a staple, e.g.:
On the top right corner
Neatly print your name, course, date, e.g.:
Very good, even excellent, and .... more than needed (real example).
MAE 4730 or 5730
HW 1, Due date
c) As noted above, please, at home, put a Staple at the top left corner. Folded interlocked torn corners fall apart. Paperclips fall off.
d) Cite your help. At the top of each problem clearly acknowledge all help you got from TAs, faculty, students, or any other source (with exceptions for lecture, text and section, which need not be cited). You could write, for example: "Mary Jones pointed out to me that I needed to draw the second FBD in problem 2." or "Nadia Chow showed me how to do problem 3 from start to finish." or "I copied this solution word for word from Jane Lewenstein " or "I found a problem just like this one, number 386.5.6, at cheatonyourhomework.com, and copied it." etc. You will not lose credit for getting and citing such help. Don't violate academic integrity rules: be clear about which parts of your presentation you did not do on your own. Violations of this policy are violations of the Cornell Code of Academic Integrity.
e) Every use of linear or angular momentum balance must be associated with a clear correct free body diagram.
f) Your vector notation must be clear and correct.
g) Every line of every calculation should be dimensionally correct (carry your units, read Appendix A of Ruina/Pratap book).
h) Your work should be laid out neatly enough to be read by someone who does not know how to do the problem. Part of your job as an engineer will be to convincingly get the right answers. Your job on the homework is to practice this. Your goal should be "solutions quality". Each problem should start on a fresh page; a new problem should not start on the same page as the ending of another problem. A solution should be self-contained, including, for example, enough of a problem restatment so that a reader need not see the original problem statement. Box in your answers. Your solution should be clear and convincing enough so that another student (who has not done the problem and does not know how to do it) can read your solution, understand it, and judge that it is correct. Your solution may be selected for posting (without your name). If you do not want your solution posted, please say so on the top of each homework.
i) Some problems may seem like make-work because you already know how to do them. If so, you can get full credit by writing in full "I can do this problem but don't feel I will gain from writing out the solution" or, in short, "Can do, don't want to." You can keep doing this unless/untill your grader/TA challenges your self-assessment.
j) Computer work should be well commented. Your name should be near the top of the computer text file. Before handing in, you should highlight (or circle with a colored pen) your name on the computer printout. At least some part of any other computer output should also include your name, printed by the computer. Highlight (or circle) your name on each page.
k) Grading and regrading. So long as you have made a good attempt at your first effort, you can get full credit by redoing a problem with 1 week of when it is returned to you.
l) Hold on to your homework. We may not record grades correctly as we go. At the end of the semester you will hand in a folder of your completed HW.
Study advice: Try to do assigned homework problems from beginning to end with no help from book, notes, solutions, people, etc., yourself without looking up even one small thing. Explain, at least outloud to yourself, every step. If you did need help, then afterwards start the problem over by yourself without looking up even one small thing. Then similarly do other problems that are like the assigned problems. Then do old prelims and exams. Finally, for A+ style studying, invent and solve your own problems.
