You will be tested on them the third day of class.

|
11 |
Equation
of Equilibrium for a point mass in 2-D. |
2. Attention Quizzes (AQ)
(5%)
Quizzes will be given after every class
during the last 5 minutes. These are given for
two reasons: one for making sure you are attentive
in the class and the other to determine if majority
of the students had difficulty with any specific
topic. This way I can repeat tough topics during
the following lectures.
3. Homework (15%)
Homework problems will be assigned at
the end of each lecture. Tuesday assignments are
due on the following Tuesday. Thursday assignments
are due on the following Thursday. Each homework
problem is worth 1 point. You are encouraged to
work together in small groups, but keep in mind
that homework is assigned in order to help you
learn and keep up with the course material. You
are expected to learn how to use MATLAB/Mathematica
in order to solve more complex problems. You
are also encouraged to do additional problems
out of the text for practice. The assigned
problems are the minimum necessary to master the
material. The only way to learn the skills
taught in this course is to apply them.
Homework may not be turned in late. Solutions
covered in class immediately after homework is
due. It's not fair to others to hold up going
over solutions because of a few late assignments.
It is strongly encouraged that you complete late
assignments for your own benefit. Please see me
if you need help with the homework.
4. Quizzes (35%)
There will be 4 quizzes graded on a straight scale
(> 90 = A, > 80 = B, > 70 = C, > 60
= D, < 59 = F). All quizzes are closed book,
closed notes. Make ups are given only with a Doctor's
note. It is your responsibility to make sure you
have no conflicts, within your control, with these
times. No ``cheat sheets'' will be allowed, but
required information for difficult equations will
be given to you. Quizzes will be returned as soon
as possible. Solutions will be discussed during
the lecture following the quiz, if time permits.
All grading discrepancies must be brought up no
later than one week after the quiz is returned.
These exams would be on Thursdays of 2nd week,
4th week, 6th week, and 8th week of the quarter
unless other days are announced in the class.
5. Project (10%)
A design project will be assigned during the quarter.
You may not consult other members of the class
(outside of your group) for assistance on the
project. You may (and are expected to) consult
the library and the instructor.
6. Final Exam (30%)
The final exam will be given during the
scheduled time. Your final grade will be no less
than one letter grade below your final exam grade.
Programming/Computer Usage
Please read the text and use on-line
help. Syntax issues are sufficiently discussed
or displayed in these resources. It is highly
recommended that you learn to use Mathematica
and Matlab on your UNIX account or a PC as soon
as possible. Each has strengths and weaknesses.
You could attend the MATLAB Workshop for further
help in MATLAB
FORMAT FOR
HOMEWORK PROBLEM SOLUTIONS
|
A. |
Make a clear statement of the problem.
Include
|
|
B. |
Draw a force diagram for all "bodies"
involved. It should
 |
show all forces involved, and
|
 |
will
be called a "free-body-diagram"
or F.B.D. |
|
|
C. |
Apply Fundamental Principles of Mechanics
|
|
D. |
Solve these equations for unknowns. Beware
of
 |
UNITS!
|
|
|
E. |
Check
the answers. Do they make sense? |
Cheating
Don’t!!
