A to and fro motion, which has been started by an initial disturbance, cannot continue indefinitely. The energy at the initial stage, given to the system, will dissipate during the motion. The resistance or obstacle encountered by a body to the vibratory motion is called damping.
The device used for damping is called dampers or shock absorbers. Since, excessive of shocks is a curse to big machineries, industries and for automated applications.
The main aim of the designers is to build shock absorbers that fully dissipates the motion or vibration that is unnecessary or else it can cause damage to the machinery. They focuses on manufacturing shock absorbers for specific uses.
These industrial shock absorbers are used in media field also. Some of its applications are :-
In camera stabilizers:-The main function of camera stabilizer is to hold the camera or mobile screen in a way that it protects the camera from the unwanted shakiness or movements.
In order to do so, camera stabilizers uses small shock absorbers which absorbs the kinetic energy produced during movements and prevents the unwanted movements in the camera.
In camera crane motion controller:- The camera crane takes camera to places or to an elevated height and angle that can’t be achieved by humans. Dampers are used in these cranes to avoid any disturbance by wind or any other external factor and completely resists the vibrations.
In other words, these small shock absorbers linearly decelerates the motion experienced by the camera or camera crane. Thus, saving the camera from any further forced motion or vibration
