MCE-371 – Vibrations


Fall 2009, SH 267, Tue/Thurs 1:00-2:50pm


Objective:       This course introduces the basic concepts of one and two degree of freedom vibratory systems. Forced and free vibration, transient and steady state response will be evaluated and applications of vibration analysis will be discussed. Practical examples will be explored throughout the semester, in order that the students can connect the classroom theory to the instructorÕs extensive practical experience in this field. At the conclusion of the course, students should expect to have a basic working knowledge of Engineering Vibration and how to apply that knowledge to practical problems they may experience in the workplace. Some computer programming is required.

Grading:        Midterm I      100 Points       Midterm II     100 Points       Final   100 Points

                        Pop Quizzes   100 Points       Homework     100 Points


  1. Homework will be assigned every Tuesday, and selectively collected the following Tuesday. Solutions will be provided either in class, via web posting, or via email (not all three). You must be present to hand in your homework.
  2. Pop quizzes will be held on Thursdays. The quiz problem will be based on the homework assigned the previous week. Quizzes will generally be closed book, closed notes. Formulas will be provided.
  3. Attendance is mandatory. Generally, only official university excused absences will be permitted. For any other absence (funerals, jury duty, etc) you should check with me beforehand to see if they will be excused. No absence, excused or not, absolves anyone of the responsibility for following the classÕ work and being fully prepared for the next attended class.
  4. Tardiness and leaving class early are both unacceptable without making proper arrangements beforehand. For those arriving late to class without a proper excuse, extra time on quizzes and exams will not be allowed, and homework will not be accepted.
  5. Exams will be closed book, closed notes. Formulas will be provided.
  6. A straight grading scale will be used (A-90/100, B-80/89, etc.) until further notice.
