ME 206
DYNAMICS
SPRING 2003
Description
Study of the motions and forces of engineering systems. Kinematics and kinetics of
particles; equations of motion. Energy and momentum methods. Introduction to rigid
body dynamics. Engineering applications.
Objectives
In general, this course supports Mechanical Engineering program objectives by
developing:
 An ability to apply knowledge of mathematics, science, and engineering in the field
of mechanical engineering
 An ability to identify, formulate and solve problems in the field of mechanical
engineering
 A recognition of the need for, and an ability to engage in, life-long learning in the
field of mechanical engineering
 An ability to use the techniques, skills, and modern tools necessary for the practice
of mechanical engineering

Glen Prater, Jr., gprater@louisville.edu, SH 200, 852-6331. Office hours: M,W,F,
10:00-11:30 and T, 9:00-12:00, or by appointment.
Text
A. Bedford and W. Fowler, Engineering Mechanics: Dynamic, 2nd Edition, Addison
Wesley, 1999.
Organization One 50 minute session (MWF 9:00-9:50, SH 208) per week devoted to lecture,
problem solving, and homework discussion.
Grading
Course grades will be based on four quizzes, three midterm examinations, graded
homework, and a comprehensive final examination. Relative weighting is as
follows:
Homework
Quizzes
Midterms
Final Exam
10%
4 @ 5%
3 @ 15%
25%
The scale below will be used to assign letter grades. These percentages may be
lowered, depending on the class score distribution. Plus/minus grades will not be
assigned.
90-100
80-89
65-79
50-64

D
Late submissions of homework will be accepted, but will automatically receive a
score of zero. Problem solutions must be neat, and include lists of assumptions, free
body diagrams, symbolic representation of the equations used, and proper units. Part
of the assignment will be graded for content, the remainder for completeness.
Reading assignments include example problems.

Grading – Continued
Unless specified otherwise by the instructor, all homework sets are due on the
Monday following their assignment. No completed examination or quiz may be
retaken. Requests to miss an examination or quiz must be submitted in writing at
least 24 hours before the scheduled date. Note that all assignments, including
homework and quizzes, must be completed and submitted to avoid a grade of
incomplete for the course.
Quiz and exam questions will strongly reflect the content of the homework
assignments. Late submissions of homework will be accepted, but will automatically
receive a score of zero. Problem solutions must be neat, and include lists of
assumptions, free body diagrams (if appropriate), symbolic representation of the
equations used, and proper units. Part of the assignment will be graded for content,
the remainder for completeness. Reading assignments include the example problems
in the text.
Ethics
Cheating and/or representation of other's work as your own is a serious breach of
professional ethics and the instructor reserves the right to apply a suitable penalty for
such infractions, including, but not limited to a failing grade for the course.
