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.
What is vibration answer?
What is vibration short answer?
Vibration means quickly moving back and forth (or up and down) about a point of equilibrium. The vibration may be periodic (having a pattern) or random. Something that is vibrating may shake at the same time. … This vibration will send sound waves to the ear and to the brain.
What is called vibration?
Vibration is the mechanical oscillations of an object about an equilibrium point. The oscillations may be regular such as the motion of a pendulum or random such as the movement of a tire on a gravel road. … Such an exposure is called hand-arm vibration exposure.
What is vibration 9th?
Vibration is a periodic back-and-forth motion of the particles of an elastic body or medium about a central position. It is also named as oscillation.
What is vibration give example?
The definition of a vibration is a movement back and forth, or an emotion sensed by another person. An example of a vibration is the feeling of two cymbals being slammed together. An example of a vibration is when one person gets the feeling that another person does not want to do something that has been discussed.
What is vibration in physics class 8?
A repeated back and forth motion is called vibration. When an object moves back and forth continuously, we say that it is making vibration. When a swing moves back and forth repeatedly, we say that swing is making vibration or oscillation.
What is vibration in sound Class 8?
Vibration is the to and fro or back and forth motion of an object. What is the length of vocal cords in men ? Answer: The vocal cords in men are about 20 mm long.
What is vibration system?
Vibratory systems comprise means for storing potential energy (spring), means for storing kinetic energy (mass or inertia), and means by which the energy is gradually lost (damper). The vibration of a system involves the alternating transfer of energy between its potential and kinetic forms.
What is vibration mode?
A mode of vibration can be defined as a way of vibrating, or a pattern of vibration, when applied to a system or structure that has several points with different amplitudes of deflection. From: Encyclopedia of Vibration, 2001.
