Course Catalog Description
ENGR 2302 Engineering Dynamics
Prerequisite: ENGR 2301 (Engineering Statics) with a grade of C or better and MATH 2415 or higher
Credit: 3 (3 lecture, 1 lab)
A continuation of Engineering Mechanics course, specifically designed for engineering majors. Topics include dynamics of
particles in two and three dimensions, Dynamics of rigid bodies in two and three dimensions, introduction to mechanical
vibrations.
Course Learning outcomes:
1. Students should be able to demonstrate qualitative and quantitative understanding of Newtonian-Euler
physics and basic equations underlying kinematics and kinetics of rigid bodies in 2D and 3D motion.
2. Students should be able to develop the skill to isolate rigid bodies and draw clear and appropriate

free-body diagrams and thereby apply these skill to solution of kinematics and dynamics problems in
2-D and 3-D.
3. Students should be able to demonstrate an understanding of conservation laws/ principles in
mechanics i.e., Law of conservation of energy, Law of conservation of Momentum (both linear and
angular) and apply these principles as an alternative method to Newton’s laws of motion in solution of
dynamics problems.
Attendance Policy
The HCCS attendance policy is stated in the Schedule of Classes. “Students are expected
to attend classes regularly. Students are responsible for materials covered during their
absences, and it is the student's responsibility to consult with instructors for make-up
assignments. Class attendance is checked daily by instructors. Although it is the
responsibility of the student to drop a course for non-attendance, the instructor has full
authority to drop a student for excessive absences. A student may be dropped from a course
for excessive absences after the student has accumulated absences in excess of 12.5% of the
hours of instruction (including lecture and laboratory time).” Note that 12.5% is
approximately 2 classes or labs for a 4 semester hour course, such as this one, which
meets for 3 hours two times. If circumstances significantly prevent you from attending
classes, please inform me. I realize that sometimes outside circumstances can interfere
with school, and I will try to be as accommodating as possible, but please be aware of the
attendance policy.

“Notice: Students who repeat a course three or more times may soon face significant
tuition/fee increases at HCC and other Texas public colleges and universities. If you are
considering course withdrawal because you are not earning passing grades, confer with
your instructor/counselor as early as possible about your study habits, reading and writing
homework, test-taking skills, attendance, class participation, and opportunities for tutoring
or other assistance that might be available.”
Disability Support Services (DSS)
"Any student with a documented disability (e.g. physical, learning, psychiatric , vision, hearing, etc.)
who needs to arrange reasonable accommodations must contact the Disability Services Office at the
respective college at the beginning of each semester .Faculty are authorized to provide only the
accommodations requested by the Disability Support Services Office."
For questions, contact Donna Price at 713-718-5165 or the Disability Counselor at each college (At
Southwest College, contact Dr. Becky Hauri, 713-718-7909). Also visit the ADA web site at:

Academic Honesty
Students are responsible for conducting themselves with honor and integrity in fulfilling
course requirements. Disciplinary proceedings may be initiated by the college system
against a student accused of scholastic dishonesty. Penalties can include a grade of "0" or
"F" on the particular assignment, failure in the course, academic probation, or even
dismissal from the college. Scholastic dishonesty includes, but is not limited to, cheating
on a test, plagiarism, and collusion.
Examinations, Final course grade, grading scale and Make-up Policy:
Three regular exams and a compulsory comprehensive final will be administered during the
semester. Make-up exams will not be given, so make every effort to take the exams on their scheduled
dates.
Note: The final examination is compulsory (no student is exempted) and once a student takes the
final examination, that student cannot receive a grade of “W” in the course.
The final grade is based on the score out of 100% that the student accumulated from the three exams, the
final exam and Homework assignments and quizzes. Here is the weighting of the categories:

interesting and informative, but spending long hours searching for sites or waiting for
graphics intensive sites to load, is not beneficial! Your best immediate source of

Assignments:
Practice problems and homework problems will be assigned from end chapter problems after every
chapter is covered. Students are strongly advised to attempt all these selected problems and other endchapter problems from the textbook. The success in courses like this one depends on once
comprehension of the subject matter and ability to solve as many problems as possible.
General Suggestions
Engineering is a vast field, ranging from the study of simple motions and free-fall to
enormously complex particle motions. In this course, the major topics we will be covering
are particle motion, work, energy and other related topics to these main course agenda. As
you might suspect, it can be easy to fall behind and, as a result, to not be ready for the
exams. Following are some general tips that may be helpful:
Learning Engineering Dynamics takes time. A reasonable guide is to allow two hours
√ of study for each hour of lecture. Heavy work and/or class loads are not compatible
with learning engineering courses.
√ Attend class regularly (!) and take generous notes during class. Ask questions.

When beginning a new chapter, It is recommend that you read through it quickly the
first time, just to give yourself a good feel for what it is about. If you are really on the
job you will have done this before the class lecture on the chapter! You will
understand what's going on in class much better if you do this.
Next, start tackling the end of chapter problems! Often, working problems facilitates
understanding much better than just reading and rereading the chapter itself.
Engineering courses are "hands on" courses - working problems is essential.
However, do not spend an inordinate amount of time on a single problem - skip it for
the time being and go on to another. Try working some of the sample exercises. They
are worked out in the chapter and are very helpful.
Get a good, scientific calculator that has scientific notation ("EE" or "EXP" key), log,
ln, x2, , etc. Business calculators usually do not have all of these features.
Review the mathematics required for the course, i.e., vector algebra, rules of
differentiation and integration, and properties of differentials as well as integrals.
Study groups can be very helpful. Keep the group small though, no more than three
or four people.
Finally, keep a positive attitude! Engineering Dynamics can be hard, but with the
right attitude and approach, you will succeed in mastering it!
It is hoped that you will find this course to be an interesting and rewarding subject which will not only
be useful in your academic major, but will give you a better insight into the many scientific challenges
we are facing today. The instructor looks forward to working with you this semester!
