3514 ME - System Dynamics
Policy Sheet Fall Semester, 2011
CRN 94332 - MWF 8:00 AM 8:50 AM Randolph Hall 221
Credit:
3 credit hours
Prerequisites: MATH 2214, ESM 2304: Dynamics Of Particles And Rigid Bodies - Vector treatment of the kinematics and kinetics of particles and rigid bodies, Newton's laws, work and energy, impulse and momentum, impact, mass moments of inertia, vibrations. If you have not passed ESM 2304, see your instructor immediately. Text: System Dynamics by Katsuhiko Ogata, Prentice Hall.
Supplement: MATLAB/SIMULINK Software
Course Objectives: Having successfully completed this course, students will be able to: Separate physical systems into component parts and identify the appropriate physical principles governing the dynamics of these component parts. Write algebraic and differential equations to describe the dynamics of these component parts and the relations between the component parts to produce the overall system behavior. Solve and interpret the dynamics equations in the time and frequency domains both numerically and analytically Describe the analogous behavior of electrical, mechanical, fluid, and thermal systems. Predict response of first-order and second-order systems without solving the equations. Develop and use transfer-function descriptions of systems to analyze the behavior of systems.
Honor Code: The honor code will be strictly enforced in this course. All assignments submitted shall be considered graded work, unless otherwise noted. All aspects of your coursework are covered by the honor system. Any suspected violations of the honor code will be promptly reported to the honor system. Honesty in your academic work will develop into professional integrity. The faculty and students of Virginia tech will not tolerate any form of academic dishonesty.

Grading Policy:
Test 1 20% Test 2 20% Homework 30% Final Exam 30% Total 100% If you are in doubt about your standing at any time, consult your instructor.
Test Policy: Tests will be given only on the scheduled days and will cover material designated by the instructor. The tests will mainly cover theoretical concepts. Closed book tests will be given unless stated otherwise.
Lecture Policy: Attendance is expected and wise, but is not mandatory. The student is responsible for any materials given in lecture or handouts and not covered by the text. Scholar will be used to distribute material.
Reading Assignments, Review, and Homework Policy: The reading assignments are chapter sections in the text. The student is responsible for all the reading, even if not covered in the lectures. Homework assignments will be announced in class and distributed through scholar. All homework problems will be collected and selected problems may be graded. The instructor may use quizzes in lieu of, or in addition to, homework problems. General concepts and directions to solutions of problems will be discussed in class. Other Items: Students having any special requirements or disabilities should see the instructor to clarify same during the first week of class during office hour or by appointment.
Office hours: MWF 1:00-2:00 pm

Homework Rules: Homework problems will be graded in a 0-5 scale. A zero or one indicates that the problem has not been turned in, or that the student has not made a significant effort to solve the problem. A four or five indicates that the student has gotten the problem (substantially) correct. A two or three will be given for those problems where the student has shown evidence of working on the problem, but has been unable to reach a satisfactory solution. Thus, even incomplete solutions should be turned in if the homework problem is called for. In general, homework will be assigned on Mondays and due a week later. Late homework will not be accepted. Assignment sheet with student's name (Last name first) must be the first page of each homework (distributed through Scholar). Homework must be stapled. Clearly identify the problem being solved. Example:
Clearly identify the final solution(s) to the problem. Examples:
or
Solution must be well organized, neat, and clean. Plots and graphics must be generated electronically. Need to label axes, plot, etc. Example:
If homework does not adhere to these rules, it will be returned with a zero grade.
