Prentice Hall 2007
General Education Objectives: All classes in pre-engineering at Dixie State College
support the general education goal of the college. After completing any pre-engineering
course, you should be able to:
• Explain and apply major concepts in the engineering sciences.
• Demonstrate knowledge of the process of engineering science and design.
• Communicate the engineering design process through oral or written assignments.
Course Purpose: The primary purpose of this course is to give each student an
understanding of the basic principles of dynamics as they relate to the different fields of
engineering.
Course Objectives:
1. The student should understand the basic physical concepts of dynamics.
2. The student should understand and be able to relate the kinematics of particles
and rigid bodies to the solution of dynamics problems in straight line and
curvilinear motion.
3. The student should understand and be able to apply Newton’s Laws to
particles and rigid bodies to solve problems related to dynamic behavior.
4. The student should be able to apply the methods of work, momentum and
energy to particles and rigid bodies associated with dynamic behavior.
Course Requirements:
Class Attendance: Attendance in class is essential to the learning of dynamics.
It is expected that the student will attend all classes. Tardiness is frowned upon by the
instructor and may invoke his ire. You will be held accountable for information
presented in class. Attendance is a part of the final grade for the class. For each class
that you miss beyond two class periods, it will reduce your attendance grade by 2% of the
12% (means that 6 absences beyond the first two (2) and you have lost 12% of your final
grade).
Reading Assignments: Reading assignments will be given on a daily basis and
are due the period after assigned. Reading assignments are shown on the course outline.
Problem Assignments: Problem assignments are given each class period and are
due as indicated on the assignment sheets handed out during the semester. Each problem
assignment will be graded for completeness and each problem worked is worth one (1)
homework point. Problem assignments are to be placed on the table at the front of the
classroom before the end of class on the date due. Problem assignments turned in after
they are due will be reduced in grade by 50 percent until the problem assignment is
returned to the student, thereafter, no credit will be given for that problem assignment.
The following rules will be followed in working and turning in homework:
1. Work all problems using a sharp black pencil on engineering computation
paper. Print or letter all work - do not write. A prospective engineer should
perform his work in a manner that would be professional. The student who
persistently turns in sloppy work will have his grade reduced on that problem
assignment.
2. Circle the problem number and separate problems to be worked on the same
page with a heavy horizontal line across the page (use a straight edge). The
course number and section should be on all problem assignments, quizzes and
examinations.
3. Always include a sketch or free body diagram where necessary. Always write
the algebraic equation(s) used preceding the numerical solution.
4. Underline your answers to problems with two distinct black lines. Red pencil
is for the instructor’s use only.
Quizzes: Short quizzes may be given during any class period on material
previously covered or material assigned for that day. A zero will be recorded for the
absent student unless previous arrangements have been made to be absent. Quizzes will
be graded on the basis of 10 points and will be included as part of the homework grade.
Examinations: Three one-hour examinations, a take home examination and a
final examination are planned during the semester. Failure to take an examination when
scheduled will result in a score of zero on that examination unless an excuse is approved
IN ADVANCE by the instructor (including College approved absences) or a signed
DOCTOR’S EXCUSE is presented to the instructor after the examination has been given
(A telephone message left on my answering machine ahead of the examination time
would be very helpful along with the doctor’s excuse.). During examinations and
quizzes, individual work is required. Any student caught being dishonest in the judgment
of the instructor during an examination or quiz will be dealt with according to Dixie
College policy as stated under Scholastic Standards (Academic Discipline Policy) in the
Official Catalog.
A. In grading examinations and quizzes, emphasis will be placed upon using the
correct approach to the problem. For example, a numerically incorrect
solution resulting from a fundamentally sound attack on a problem will
receive more credit than a numerically correct answer arrived at from an
unsound analysis of the problem.
The last week of classes may include the last hour examination and /or
problem assignments.
C. All makeup examinations, if any, will be given at a time that is convenient to
the instructor and only to those with approved excuses.
B.
Course Grading: Your final grade for the class will be based upon problem assignments,
quizzes, hour examinations, take home examination, and a final examination. The
weighting for determination of the final grade will be:
Problem Assignments and Quizzes
12%
Attendance
10%
3 - Hour Examinations
51%
Take Home Examination
10%
Final Examination
17%
Letter grades for the course will be assigned based upon each student’s final
course average compared to the indicated percentages below:
Percentage
Grade
Percentage
Grade
Percentage
Grade
93-100
A
80-82.9
B67-69.9

B+
73-76.9
C
60-62.9
D83-86.9
B
70-72.9
C<60
F
The instructor may adjust the grading scale percentages downward if he thinks it is
warranted based on a comparison to other students in the class.
Student Progress: After each examination, a new progress sheet will be posted. The
progress sheet will identify you by the eight digits of your Dixie College assigned
number and will show your scores and grade up to that point in the semester. If you do
not want your grade posted with your Dixie College assigned number, notify the
instructor in writing and give him an alternative eight digit number or a statement
indicating that you do not want your grade posted.
The instructor reserves the right to alter this syllabus and announce changes in class.
Non-attendance will not be an excuse for missing changes. Leniency on my part at times
regarding class policies does not constitute a wavier of those or any other class policies.
Cell Phones must be turned off during class. Abuse of the cell phone policy will
result in expulsion from the class.
If you are a student with a physical or mental impairment and would like to request
accommodations, please contact the Disability Resource Center (652-7516) in Room 201
of the Student Services Center. The Disability Resource Center will determine your
eligibility for services based upon complete professional documentation. If you are
deemed eligible, the Disability Resource Center will further evaluate the effectiveness of
your accommodation requests and will authorize reasonable accommodations that are
appropriate for your disability.
