Vibration can be desirable: for example, the motion of a tuning fork, the reed in a woodwind instrument or harmonica, a mobile phone, or the cone of a loudspeaker. In many cases, however, vibration is undesirable, wasting energy and creating unwanted sound.

2022年10月26日 · Examples of Forced Vibration: A harmonic or non-harmonic disturbance can be used as a periodic input for the forced vibration. Shaking of washing machine due to imbalance. Transport vibrations that are induced by an engine or uneven road. The vibration of a moving vehicle is forced vibration, as the engine, springs, road, etc., continue to ...

Any motion that repeats itself after an interval of time is called vibration or oscillation. The swinging of a pendulum (Fig.) and the motion of a plucked string are typical examples of vibration. The theory of vibration deals with the study of the oscillatory motion of bodies and forces associated with them. Vibration Example

Examples of beneficial applications of vibrations include ultrasonic probes, both for medical application and for nondestructive testing. The picture shows a medical application of ultrasound: it is an image of someone’s colon.

•Examples are many: •We hear because our eardrums vibrate •Human speech requires the oscillatory motion of larynges •In machines, vibration can loosen fasteners such as nuts. •In balance in machine can cause problem to the machine itself or …

2023年8月23日 · Mechanical vibrations refer to the oscillations or repetitive motions of a mechanical system about an equilibrium position. These vibrations can occur in various engineering systems, including machinery, structures, …

2024年12月23日 · Vibration, periodic back-and-forth motion of the particles of an elastic body or medium, commonly resulting when almost any physical system is displaced from its equilibrium condition and allowed to respond to the forces that tend to restore equilibrium.

Examples of vibrations include a swing moving back and forth (like a pendulum) or a mass bobbing up and down on a spring. The video below demonstrates this periodic back and forth motion using the example of a swing set.

2023年11月9日 · Plucking of strings in a musical instrument, shaking of a building during an earthquake, resonant vibration of a tuning fork when struck, rhythmic beating of Human Heart, etc.. are all examples of vibrations.

Vibrations: Vibration is the periodic back and forth motion of elastic media particles. There are different forms of vibration: Forced vibration; Free vibration. etc. Example of vibrations: The weight dangling from the spring is an example of a free vibration. If the spring is dragged down as seen on the left, it will vibrate vertically.
