Grading Policy:

   Homework      25% (drop the worst)
   Projects           10%
   Midterms         40%
   Final                25%



Class Objectives:

Upon completion of this course, students should be able to:

1) Use Newton's Second Law and free body diagram approach to model vibratory systems
2) Solve differential equations and eigenvalue problems for determining the dynamic response (with correct units) of vibratory systems
3) Understand the physical and mathematical significance of:
        natural frequencies and mode shapes
        free and forced response
        resonance
        damping
        superposition
        lumped parameter vs continuous systems
        linear vs non-linear systems
4) Use appropriate analytical, numerical and computational tools
5) Understand experimental and data analysis techniques
6) Design mechanical systems with prescribed vibratory performance
