Vibrations
A mechanical wave requires a material medium in order to travel, vibrations are able to move through the air unaided. While they have different traveling mechanisms, a vibration can be considered as a type of mechanical wave.
On free vibration the beam or structure is not suffering influence of forces (Beam on space). In forced vibration the structure is under presence of force example bridges. Later on will you discover the free vibration is important to obtain natural frequencies and mode shapes. the difference b\w forced and free vibration can be understand by the examples.............a) the vibration of a pendulum is free vibration which needs no external force to vibrate. b) the vibration of a machine like a drill is forced vibration which needs an external force to vibrate.
Amplitude- The maximum distance to which an oscillating or vibrating object moves from its central position is called amplitude. Vibration- Sound is produced by rapid -to and -fro movements ,called vibrations.
Sound, which is air vibrations.
Vibration exciters are active systems and can generally be used for high-precision excitation of structures to vibrations and for the specific reduction of structural vibrations.
If you excluded two tin cans with a string, alltelephones change sound vibrations into electrical vibrations.
Sound and vibration are both mechanical vibrations of a medium, and thus demand a medium for their travel. Note- they vibrate the medium - they are not independent of the medium as is light.

An engine when running will vibrate. If directly fixed to the supporting structure then this vibration would transmit through the vehicle or structure body. These vibrations lead to noise and mechanical damage in adjoining structures. The engine mount is typically a rubber to metal bonded component which is used to 'mount' the engine onto the structure. The rubber element is used to absorb or 'dampen' the vibrations, reducing noise and increasing the service life of the surrounding structures and components. Try searching for 'anti vibration mountings'. Some companies which manufacture engine mounts are: - AV Industrial Products Ltd
