However, mechanical vibrations can transmit for long distances, and by very circuitous routes through the structure of a building, sometimes resurfacing hundreds of feet from the source. Firstly, the need to reduce the transmission of vibration from a machine to the structure supporting it.
The most basic problem of interest is the study of the vibration of a one. In nature, vibrations are also used by all kinds of different species in their daily lives.

Mechanical vibrations solution methods for the generalized eigenvalue problem these slides are based on the recommended textbook. If we examine a freebody diagram of the mass we see that an additional force is provided by the dashpot. The force is proportional to the velocity of the mass. This implies that the natural frequency of the supported system must be very small compared to the disturbing frequency. A vibration problem can also be nicely described by the same source path receiver model we previously used to characterize the noise control problem.
