VIBRATION TABLE WITH RECORDER
Aim:
To determine transmissibility of forced vibrations and to analyze all types of Vibrations with
its frequency and amplitude
Apparatus:
Vibrating table.
Description:
Vibration:
When elastic bodies such as a spring, a beam and a shaft are displaced from the equilibrium
position by the application of external forces, and when released, they execute a Vibrating Motion.
This is due to the reason that when a body is displaced, the internal forces in the form of
elastic or strain energy are present in the body. At release, these forces bring the body to its original
position
Time Period:
It is the time interval after which the motion is repeated itself. The period of vibration is usually
expressed in seconds
