Vibration refers to mechanical oscillations about an equilibrium point. The oscillations may be periodicsuch as the motion of a pendulum or random such as the movement of a tire on a gravel road.
Vibration is occasionally "desirable". For example the motion of a tuning fork, the reed in a woodwind instrument or harmonica, or the cone of a loudspeaker is desirable vibration, necessary for the correct functioning of the various devices.
More often, vibration is undesirable, wasting energy and creating unwanted sound - noise. For example, the vibrational motions of engines, electric motors, or any mechanical device in operation are typically unwanted. Such vibrations can be caused by imbalances in the rotating parts, uneven friction, the meshing of gear teeth, etc. Careful designs usually minimize unwanted vibrations.
The study of sound and vibration are closely related. Sound, or "pressure waves", are generated by vibrating structures (e.g. vocal cords); these pressure waves can also induce the vibration of structures (e.g. ear drum). Hence, when trying to reduce noise it is often a problem in trying to reduce vibration.

How does sound occur?
the lenght of the wave is depending on the vibration.
What is the number of vibration that occur in a second time interval?
frequency
What is vibrating?
Vibrating is a feeling of rapid movement. Vibration can occur during earthquakes, tsunamis.
The is the time it takes for one full vibration of a particle in a medium.?
Vibrations are oscillations that occur about an equilibrium point. The "period" is the time it takes for one full vibration of a particle in a medium.
What happens when a vibration interacts with matter?
When a vibration interacts with matter, it can induce various effects depending on the nature of the vibration and the properties of the material. If the frequency of the vibration matches the natural frequency of the material, resonance can occur, leading to amplification of the vibration. If the vibration is of sufficient intensity, it can cause the material to deform, break, or generate heat. Additionally, vibrations can also induce changes in the electrical and magnetic properties of the material.
In which part of truck the free vibration occur?
This question is missing a massive amount of background info required to answer.
Why the strings of lower tones are thicker or heavier?
So, the sound can be lower. It has to be like that because it has to create more vibration waves. The thicker/heavier the strings are, the more vibration waves occur, which makes the tone lower.
What could cause a vibration in front end of a 95 b2500 5.2l w positraction while driving the vibration does not occur all the time but it is starting to happen more frequently?
It lones to move very jittery and uncontrolably.
What is hering's vibration?
Hering's vibration refers to an optical illusion characterized by the apparent movement or shimmering of fine lines or textures when viewed. It is thought to be caused by the eye's lateral inhibition processes and can occur when looking at repetitive patterns or gratings.
Why do so many earthquakes occur along plate boundaries?
It is because the maximum vibration is in that area. The plate boundaries receive the maximum tremor.
Why vibration occur in turbine?
2 main reasons: 1. Imbalance of the turbine, 2. Shock waves from the air (if it's spinning fast enough)
What is the relationship between music and engineering?
They both deal with vibration and harmonics. Music uses the vibration of strings, membranes, vocal cords etc to create notes which are combined to form chords and music. Engineering must account for vibration and harmonics which occur naturally from movement in the earth, the wind and other applied forces. These vibrations and harmonics, if not accounted for can be destructive, even catastrophic.
