If magnitude is considered as the vertical dimension of sound, then the horizontal dimension is that of the time behaviour of sound. What is common to all sound is a pattern of change over time called ...

Here we consider a harmonically-excited (point load on the top floor) four-DOF building model using modal uncoupling. From this procedure we are able to see that the response of the building is ...

How to Remove an LS3 Harmonic Balancer or Vibration Damper You will need two special tools to remove and replace the stock LS3 harmonic balancer, we show what they are and how to use them.

In the following animation, we see this four-step process to aid us in interpreting the resonance response of a single-DOF oscillator to harmonic excitation. From this, we see that the response ...
