**Homework policy, assignments, and
reading guide
TAM 203, Spring 2008 **

**Homework policy: **To get credit, please do the
things listed below on every homework.

a) Homeworks are duetwo lectures after the date assigned in lecture. You need not bring your homework to the front of the class, hold on to it. It will be collected from the class at the start of class. Homework handed in after the start of class or later will be marked "late." For example, you should have the first homework assignment (due Jan 29) in hand at your seat, following the policies below, at the start of lecture on Tuesday January 29.

b)On the top right cornerneatly print the following, making appropriate substitutions as appropriate:

HW probs 1-5, Due January 29, 2008

TAM 203

Section 1 at 12:20

TA: Mahesh Jones

b)STAPLEyour homework at the top left corner.

c)At the top clearlyacknowledge all helpyou got from TAs, faculty, students, or ANY other source (but for lecture, text and section). 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 the solution of Jane Lewenstein " 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:be clear about which parts of your presentation you did not do on your own.Every use of force, moment, momentum, or angular momentum balance must be associated with a clear correctViolations of this policy are violations of the Cornell Code of Academic Integrity.

d)free body diagram.Your

e)vector notationmust be clear and correct.Every line of every calculation should be

f)dimensionally correct(carry your units, see text Appendix A).Your work should be

g)laid out neatlyenough to read by someone who does not know how to do the problem. Part of your job as an engineer is not just to get the right answer, but convincingly so. That is your job on the homework as well.

h)Some problems may seem likemake-workbecause 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". You can keep doing this unless/untill your grader/TA challenges your self-assessment.

i)Computer work should be well commented. At the top the computer text file should include your name which you

later highlight or circle with colored pen. At least some part of any computer output should also include your name,

printed by the computer. Also highlight this or circle it with colored pen.

j)At least one problem in each assigment should be "solutions quality". This should start on a fresh page, use single sides, and not have a new problem start on the same page. It should be self-contained, including, for example, enough of a problem restatment so that a reader need not see the original problem statement. It should be clear and convincing enough so that another TAM 203 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. The first word of this solution should be "SOLUTION".

**Problems** subject to change until 3 AM of the morning after

(e.g., January 22 assignment due January 29 is not set in stone until January
23 at 3 AM)
