COURSE INFORMATION ENGN 37 - Engineering Mechanics - Dynamics Please check my current schedule for the section number and CRN number. . Prerequisites ENGN 36 (Statics)
Textbook & Materials
Almost any edition of this textbook is acceptable. (Ask if you are unsure.)
COURSE DESCRIPTION This is an introductory course in
Dynamics. The motion of particles, systems of
particles, rigid bodies and systems of ridid bodies is analyzed from
the perspective of kinematics, (the description of a
rigid body's position, velocity and acceleration,) and
kinetics, (the relationship between the forces acting
on a rigid body and its velocity and
acceleration.) Problems solutions applying |

ASSIGNMENTS
The reading assignments will include the week's overview (just a page or two) and anywhere from 2-10 sections of a chapter in the text book. These reading assignments are extremely important, possibly more important than the homework sets.
The problem assignments will pertain to the reading material. There will be either one or two sets of problem assignments per week, each consisting of 3 to 4 problems. (This means a maximum of 8 problems in a week. However, some of these problems may be very time consuming!) These problem sets are not to be turned in, nor will they be graded. However, to learn Dynamics and in order to pass the midterm and final, you must understand and be able to do these problems. There will be hints for each problem and the solutions are available to you. I encourage each student to make every attempt to solve the problem on their own before resorting to looking at the hints. Looking at the solutions should be the very last resort. A student will learn a lot more by following this advice. Ultimately, it is the student's responsibility to ensure that they understand how to solve each problem.
Students are encouraged to communicate with each other via the discussion forum. Use it to get help from other students. Use it to give help to other students. Use it to give others your own insights and thoughts on the class material. The instructor will be monitoring the discussions; however she will give input only as needed. The discussion board is primarily for the students to communicate with each other. Students are also encouraged to ask questions about any problems that they don't understand, or come and get extra help during office hours in addition to posting on the discussion forums.

QUIZZES & EXAMS Quizzes . These quizzes will be taken online. They are meant to be learning tools: You will have 3 opportunities to take them and your score will be the highest of the 3. (If you score 100% on the first time attempt, you do not have to take the quiz again.) . You should view these quizzes as interactive learning tools rather than quizzes to stress about. You just need to be sure to take the quiz before it closes or you will get zero points for it! Please do not ask me to open a quiz for you if you do not take it before it closes. . Please note that the due date for quizzes is the Friday of the week in which they appear. However, they will generally close at a later date. So you may actually submit a quiz past its due date. But you will not be able to submit the quiz past its close date. ...
Quiz #0 (CCSFmail) .. EXAMINATIONS Students are required to bring a valid picture identification to the exams. Valid identification is limited to a California drivers license, a California identification card or a passport. The dates of these exams
can be found here. Make-up exams are given only for extremely extenuating circumstances that can be documented. If you have special circumstances you may arrange to take these exams at an official testing center. Note: Please mark your calendars now for these exams. If you have a scheduling issue you must contact me by the third week of the semester. . You should expect the exams to be closed book/closed note, although this is subject to change at the last minute. In either case, you will be allowed one single-sided sheet of paper no larger than 8.5" x 11" with no staples, glue or tape. . Exams are graded for correctness of solution and for clearly showing the method of solution. Communication skills are just as, if not more, important than the technical skills that you learn in this class. Your grade will suffer if you cannot present a clear, legible solution. At the completion of any testing
time (quizzes included) I will announce that the test
is over and that you should put your writing
implements down. Your exam will not be graded if you
do not put your implement down immediately. If your
exam is not graded you will receive zero points for
it. Midterm Exam . Final Exam . . CHEATING POLICY

GRADING
Your course grade will be determined according to the following:
Quizzes (online)................................20% Midterm (on campus)........................40% Final (on campus)..............................40%
90 - 100 %........................................A 80 - 89 %........................................B 70 - 79 %........................................C 60 - 69 %........................................D below 59 %.......................................F
I may curve grades if it will be to students' advantage. Please do not email me asking for any special considerations. Your grade will be based solely on your performance on the quizzes and exams. Also, please do not email me requesting that I send your grade. You will need to wait until the school officially publishes it. |

IMPORTANT NOTE ABOUT GRADING IN THIS
CLASS
Any FBD (Free
Body Diagram) that is not done properly and in color
will receive 0 points. Yes, that's right: zip,
zero, nada, sifr
points. Use a vivid green color for the body
and a vivid pink for the forces. Oftentimes,
the FBD is worth half of the credit on a problem,
and so this is very significant.
