Homework guidelines: Homeworks are dueTuesday at noon in Thurston 102 starting on Sept 3. On every homework assignment please do the things listed below. After a few weeks of getting used to these you will have to follow all of them to get any credit for homework.
a) On the top right corner neatly print the following, making substitutions as appropriate:
Sally Rogers
HW 1 Due Sept 3, 2002
TAM 202
Section 13, Thursday at 10:10
TA: Jane Smith
b) STAPLE your homework in the top left corner.
c) At the top clearly acknowledge all help you got from TAs, Faculty, students, or ANY other source (but for lecture, text and section only). Examples could be "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 basically copied this solution from a tau beta sigma frat file." etc. If your TA thinks you are taking too much from other sources he/she will tell you. In the mean time don't violate academic integrity rules by being unclear about what of your presentation you worked out on your own.
d) Every use of force or moment must be associated with a clear correct free body diagram.
e) Your vector notation must be clear and correct.
f) All computer output should have your name clearly visible, as printed by the computer (e.g., title plots with your name, put your name in a comment in the first line of any .m files, etc.)
g) Every line of every calculation must be dimensionally correct. (Carry your units.)
h) Your work should be laid out neatly enough to easily follow. Part of your job as an engineer is not just to get the right answer, but to communicate its justification clearly. So that is part of your job on homework as well.
