**Homework policy, assignments, and
reading guide
TAM 203, Fall 2004 **

**Homework policy: **Homeworks are due at the
start of tuesday lecture (but for after fall break and Thanksgiving when they
are due on Thursday). You need not bring your homework to the front of the
class, it will be collected from the class at the class start. To get credit,
on every homework assignment please do the things listed below.

a)On the top right corner neatly print the following, making appropriate substitutions as appropriate:

Sally Rogers

HW 1 Due Aug 31, 2004

TAM 203

Section 1 at 12:20

TA: Matthew Smith

b)STAPLEyour homework at 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). 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 posted solutions." 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 correct free body diagram.

d)Your vector notation must be clear and correct.

e)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.)

f)Every line of every calculation should be dimensionally correct (carry your units).

g)Your work should be laid out neatly enough 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)

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". You can keep doing this unless/untill your grader/TA challenges your self-assessment.

**Reading suggestion: **Do a quick read of the material for the
lectures before the lectures. This is the material associated with the homework
due the next week.

**Homework 1, due Tuesday August 31 at the start of lecture: **Solutions

**Reading
guide:**

Matlab book:You should know all the tutorials thoroughly. You should know the ODE section. You should skim the rest of the book so you know what is there, at least glance at every page.

Dynamics text part I:*First two tables inside the cover: Without studying them explicitly, you will learn all that's in these tables as the semester progresses. Read through them quickly at the start of the semester and check your progress occasionally as the semester progresses. *Preface: Read and absorb the "guide to student" and pseudo-code pages. *Chapter 1: Read and understand. *Chapter 2: You need to know all of this vector material well.

**To hand in: **Consider
the two Matlab files below which we assume are both in the same directory on
your computer.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %These 4 lines are in a script file function zdot=iknowthis(t,z) [t,z]=ODE23('iknowthis', [0 2*pi], [1 0]); % These five lines are in the file iknowthis.m plot(z(:,1), z(:,2)) z1 = z(1); z2 = z(2); axis('square') z1dot= z2; z2dot= -z1; %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% zdot=[z1dot, z2dot]';

**BONUS POINTS: ** Due Dec 10. Hand in to Matt Smith. Write from 1 to 5
candidate final exam questions. Write clear complete solutions. Hand writing
and clear hand-drawing are fine. These cannot be taken from any books or from
any old exams. Questions can be of any style that you think is appropriate
(even multiple choice or essay, if gradeable).
