Vibration

Vibration

1. Simple Harmonic Motion

   • The movement is periodic In absence of friction Produced by a restitution force
   • key physical properties
     • Amplitude
       • Period
         • Frequency
           • Angular displacement
             • Angular frequency
   • Hooke’s Law

2. Motion Equations

   • The vibrations of the SHM can be studied as waves because we have an amplitude of motion, a period and a frequency of oscillation
     • Position as function of time.
       • The position (x) will be given in meters and the time (t) in seconds.
     • Velocity as function of time
       • the maximum velocity (t3) will be at the equilibrium position
     • Acceleration as function of time
       • Its basic unit is meter per second square

3. Wave Phenomena

   • • frequency (f) and period (T).
       • inverse of the frequency
         • apply them for the spring-mass ensemble
