Course Learning Objective:
The main objective of this course is to provide engineering
juniors and seniors with conceptual and analytical skills required for modeling
and analyzing vibrating mechanical systems for design, maintenance and testing
purposes. This objective supports the Clarkson ME and AE programs objectives
stated in the MAE Student Handbook (see
Section 4.3.2, Tables 5.1-2) and the relevant ABET Criteria.
Course Learning Outcomes:
Engineering Content (ABET): Eng. Science: 3 credits; Eng. Design:
0 credit
1. Students will learn how to develop
vibration models for mechanical systems using mass, stiffness and damping of
mechanical systems. [ABET Criteria a,
e, and g]
2. Students will gain experience in
deriving governing equations from Newton's Laws of motion and energy
principles. [ABET Criteria a, e]
3. Students will be able to model a
vibrating mechanical system, develop and solve its governing equations in order
to obtain the response of the system under various types of excitation
conditions. [ABET Criteria a, e, and k]
4. Students will learn how to interpret the
response of a mechanical system and use the response information in its design
and testing. [ABET Criteria b]

Note:
Grad students may be asked to do
additional problems in the exams and/or special assignments.
Important Note: All exams are cumulative.
Changes:
This syllabus
may be subjected to some changes. If there is a planned change (e.g. exams
time/place), it will be announced in class in advance.
Homework Assignments:
Homework problems will be assigned after completing relevant
lectures. Assignments will normally be returned to the head TA (to a collection
box outside his office) by 5:00pm Fridays, except announced otherwise (due to
holidays, breaks, special considerations, etc.). Answers to some of the
homework problems are listed in the textbook (starting at page 648). Solutions
will be emailed to students. Graded homework papers will be returned by the TA
(in a box outside his/her office).
Policies:
Examination and Homework
Policy: Final grades
will be determined on the basis of class average and standard deviation. No
make-up examinations will be given, the percentage of missed examination points
will be added to the final examination percentage for students with official
excuses (explained in a letter from the office of the Dean of Students). No
late homework will be accepted, since solutions to homework questions will be
posted/emailed after due dates. The percentage of missed homework assignment
points will be added to the final examination percentage for students with
official excuses (explained in a letter from the office of the Dean of
Students). All examinations are closed-book. The student can bring a formula sheet (8.5×11 in., both sides, only
formulas, no other information (no text, plots, figures, drawings, problem
solutions/outlines, etc.) along with her/him in each examination. No
hand-held computers and/or no networkable devices (e.g. cell phones, smart
phones, tablets, etc) are allowed in exam rooms. A calculator can be used in exams, however no class related
data/programs/formulas are to be stored in the calculator. During examinations,
no exchange of calculators is allowed.
Ethics:
No form of academic dishonesty will be tolerated.
Attendance Policy:
The student is expected to attend all classes. An attendance
sheet will be passed time to time. Attendance record may play a role for
borderline cases.
