Wolf,

The study of sound and vibrations are closely related. There are two types of vibrations: free and forced. We need to study forced vibrations.You would perform a Sine test or a random test. Remember, vibration acceleration is a vector with magnitude expressed in units of meters/second(squared).The gravitational acceleration, g equals 9.81 m/s (squared). You woul need to use a differential equation and Newton's Second Law. This is hard to explain,but if you go to Wikpedia. Search vibrations and it will get you started. Flash backs from Calculus & Differential Equations is scaring Tron!
Tron Out!!!
