day of class.
Course Description:
Analysis of bodies in motion; kinematics and kinetics of particles, systems of particles and rigid bodies.
Prerequisite(s): ENGR 2301 and MATH 1720.
Course Learning Outcomes:
Upon successful completion of this course, students will:
1. Express dynamic quantities as vectors in terms of Cartesian components, polar coordinates, and normaltangential coordinates.
2. Compute mass moments of inertia for systems of particles and rigid bodies.
3. Solve kinematic problems involving rectilinear and curvilinear motion of particles.
4. Solve kinetic problems involving a system of particles using Newton’s Second Law.
5. Apply the principles of work and energy, conservation of energy, impulse and momentum, and
conservation of momentum to the solution of engineering problems involving particles and systems of
particles.
6. Solve kinematic problems involving the translation and rotation of a rigid body.
7. Solve kinetic problems involving planar translation and rotation of rigid bodies.
8. Apply the principles of work and energy, conservation of energy, impulse and momentum, and
conservation of momentum to the solution of engineering problems involving rigid bodies in planar
motion.

Course Instruction and Assignments
1. Backboard Vista, at http://ecampus.unt.edu, will be used for posting the course materials and instructions,
assignments, submission of assignments, email communications about the course, and the course gradebook.

2. Each week homeworks should follow these guidelines.
 The hand-written homework must be turned in at the beginning of class.
 Late homework submittals will not be accepted without prior authorization.
 Write on one side of page only.
 Submitted work must be legible and presented in a logical, easy-to-follow manner or it will be graded as
zero. Model solutions will be shown in the class.
 Solutions to all homeworks will be provided on Blackboard.
3. Discussion and exchange of ideas are important parts of the learning process and I encourage collaboration
in a community of scholars. However, you must be sure the work you submit for grading is your own.
Submitted works that are copies from solution manuals or website solutions or your classmates will be
treated as plagiarism.
4. Be sure to check Blackboard Vista and the course email at least every other day, if not daily. All
communications related the course will be made through the Blackboard site.
5. Attendance is required for all class hours.
6. No make-up on quizzes and homework assignments.
7. No make-up will be given for the scheduled exams, unless the student has a legitimate excuse documentation
(e.g., letter from court clerk that he/she must appear in a court, letter from physician that he/she is sick,
etc.) then your score on the final exam will be substituted for the missed exam score; otherwise, the
missed exam will be scored as 0. Only one such substitution is permitted during the semester.
Exams and Quizzes
Class exams and quizzes are written and closed textbook and notebooks. A copy of the fundamental equations
of dynamics will be provided.
It will be helpful to bring a ruler for solving graphical problems. Laptop or an iPhone or iPad or any other
handheld computers and cell phones during the exams and quizzes are not allowed. Of course, you are allowed
to bring a scientific/engineering calculator. However, sharing calculators during the exams will not be permitted.
Grades are based in part on the student's ability to communicate. You must present your entire solution in an
orderly way for each problem. Full grade points will not be assigned only on the final answers with correct
steps. You must show the complete process of your solution. Partial credits will be assigned for correct steps
that have been taken in a solution.
Requests for the review of a graded exam problem must be submitted in writing no later than the next class day
following the return of a graded exam. The graded exam should be attached to your request and you must
explain your reason for requesting a grade review. In this matter, the review is not limited to a single problem
requested by the student. Upon review, the exam score may increase, remain the same, or decrease.
An I (incomplete) grade is given only for extenuating circumstances and in accordance with University and
Departmental Policies.

Disabilities Accommodation:
The University of North Texas complies with Section 504 of the 1973 Rehabilitation Act and with the Americans
with Disabilities Act of 1990. The University of North Texas provides academic adjustments and auxiliary aids to
individuals with disabilities, as defined under the law. Among other things, this legislation requires that all
students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of
their disabilities. If you believe you have a disability requiring accommodation, please see the instructor and/or
contact the Office of Disability Accommodation at 940.565.4323 during the first week of class.
Additional Class Policies
1. The Student Evaluation of Teaching Effectiveness (SETE) is a requirement for all organized classes at
UNT. This short survey will be made available to you at the end of the semester, providing you a chance
to comment on how this class is taught. I am very interested in the feedback I get from students, as I
work to continually improve my teaching. I consider the SETE to be an important part of your
participation in this class.
2. The UNT Catalog procedures on cheating and plagiarism will be vigorously enforced. It is the duty of
each student to protect their work so it is not available to others for submission as their efforts. This is
especially true of files that are generated on the computer. Students that knowingly allow others to use
their work are partners in this unethical behavior. All rules relating to academic dishonesty will be
5
enforced in accordance with University policies.
3. State common law and federal copyright laws protect this course lectures and materials. They have my
own original expression and revisions to the textbook author(s) and I record them at the same time that
I deliver them in order. Whereas you are authorized to take notes in class, thereby creating a derivative
work from my lecture, and/or make a print of my lecture notes/slides. The authorization extends only to
making one set of notes for your own personal use and no other use. You are not authorized to record
my lectures, to provide your notes to anyone else or to make any commercial use of them without
express prior permission from me.
4. This syllabus is subject to change at any time during the semester with changes to be announced during
the class hours.
5. Cell phones, iPhones, iPods, iPads, laptops must be turned off or in silent mode before the start of the
class and left in your pocket, purse, or book bag.
