COURSE DESCRIPTION
In the prerequisite course, Statics, students learned how to set up free-body diagrams and determine forces and moment
acting on rigid bodies in equilibrium. This course develops the student's ability to solve non-equilibrium problems.
Vector analysis, trigonometry, and calculus are used as tools that make possible the analysis of advanced problems
involving the motion of objects. The first component of the course covers particle motion (translational motion
kinematics, and kinetics via general equations of motion, energy methods, and conservation of momentum). The use of
software in the analysis of a particle dynamic system will also be covered. The second component of the course covers
rigid body motion (translational and rotational kinematics, and kinematics via general equations of motion, energy
methods, and conservation of momentum). For rigid body motion, the use of software in the analysis of a simple rigid
body dynamic systems will also be covered. A final course project dealing with the analysis of a mechanism, also
utilizing analysis software, will be covered.
Prerequisite: Statics (EG200)
TEXTBOOK
Engineering Mechanics: Statics and Dynamics, R.C. Hibbeler, 12th Ed, Prentice Hall, ISBN-13: 978-0-13-814929-1
COURSE OBJECTIVE
The objective of this course is to extend the student's study and understanding of Engineering Mechanics beyond statics to
the mechanics of motion. Fundamental concepts of motion are covered, i.e. kinematics and kinetics of particles and rigid
bodies, work and energy principles, rotational motion, mass moment of inertia, impulse and momentum. Three principle
methods are extensively covered: Newton’s 2nd law, energy and work methods, and impulse and momentum methods.
The knowledge gained in the course supports and prepares the student for advanced courses which utilize dynamical
analysis (Engineering Design III, Control Systems Analysis, Design of Machine Components, Vibrations, and Capstone
Design).

CLASS ATTENDANCE AND PARTICIPATION
Class attendance is required. Class attendance will be taken for federal reporting purposes. In this course you will be
expected to act in a professional manner. Among other things, this includes showing up on time prepared for the task at
hand. This shall include not just being on time for class, but also for any and all additional outside meetings you will have
with group work. Active participations in class activities are expected. Classroom activities such as chatting, use of
computer, ipod, cell phone and other electronics are not allowed.
Note that if you are more than five minutes late for class you will be marked absent. A reasonable absence is allowed
only if informed in advance and for a justifiable situation.
HOMEWORK POLICY
Homework is assigned approximately every week. Talk to me in advance if you have reasonable reason(s) for not being
able to turn in your homework on time. To be fair to all students, late homework or other assignments are given a 33%
reduction in points per day that the homework / assignment is late. A “day” is defined as 24 hours, beginning at the start
of class time.
ACADEMIC HONESTY
While it is assumed that no student/group would submit any material, be it homework, tests, or any other assignment for
grading which is not solely her/his own work, the following policy shall be implemented in cases of academic dishonesty:
First offense, all persons involved will receive no credit for the assignment or test.
Second offense, all persons involved will receive a grade of F for the course.
Please note that I am required to report all offenses to the Provost.
However, homework or other assignments are encouraged to be done in a small group environment with discussions and
exchange of ideas, as long as understandings are achieved, rather than simply copying.
STUDENT WITH DISABILITIES (ADA Compliance)
If you wish to receive Academic Accommodations at Daniel Webster College for this course, please contact the Office of
Academic Affairs at academicaffairs@dwc.edu or 577-6615 to arrange a meeting within the first two weeks of the semester.
The meeting is extremely important, as it allows us to prepare your accommodations for the balance of the semester.
Should you not wish to receive accommodations, or fail to arrange a meeting, you will be subject to all academic
standards in this course.
Please note: In order for a student to be accommodated for a disability under ADA law, the individual seeking disability
accommodations must disclose to the appointed disability coordinator. Disclosure to a staff, faculty or other campus
affiliate does not determine eligibility or grant a student reasonable accommodations.
PEER-TUTORING RESOURCES
Daniel Webster College offers various tutoring resources for all students to utilize. If you feel you need tutoring in a
course that you are currently enrolled, please contact the Dean of your School of study to make an appointment to review
your needs. Your Dean will work closely with you and our Peer-Tutoring Coordinator to arrange appropriate tutoring as
well as, if deemed necessary, to develop an academic plan with you that will assist with keeping you on track to achieve
your educational goals. Should you need Writing or Math/Science Support, you will be referred appropriately to the
Writing Center and the Math/Science Support Center for further assistance.
COURSE OUTLINE
Homework problems from the text will be assigned on a regular basis and are subject to change. A limited number of
other assignments not in the text might be given as supplemental exercises. It is expected that the interested student will
endeavor to solve these problems. Remember that you cannot adequately learn this material without practicing the
methods. In addition, a Particle Dynamics Project will be assigned during the course and will involve the use of
commercial software (for example, Excel, MathCad, or MatLab) in its implementation, and will require a detailed final
report. Also during the course, you will be introduced to SolidWorks Motion Analysis (an add-in analysis tool within
SolidWorks). Associated with the use of SolidWorks Motion Analysis, one (1) particle and one (1) rigid body analysis
projects will be assigned. A final course project, entailing the analysis of a mechanism and utilization of SolidWorks
Motion Analysis, will be assigned. The course project will also involve a detailed final report with verbal presentation.
Finally, in support of the student evaluation process, there will be two (2) Quizzes, one (1) midterm exam, and one (1)
comprehensive final exam.
