what is difference between vibratory and oscillatory motion

vsraghuvar

oscillatory motion can be sketched using sine curves.

amplitude makes much difference in cases of oscillation and vibration.

plz vote me

ill get back to u when i get m,ore information

i think in vibratory motion amplitude is very small...while in oscillatory motion its not

v.sabarish

Looks convincing, but I have a doubt...
small, large are always relative...... you cannot say that something's absolutely small or absolutely large......
then how do you distinguish??

Vibration refers to mechanical oscillations about an equilibrium point . The oscillations may be periodic such 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 minimise unwanted vibrations.

The study of sound and vibration are closely related. Sound, pressure waves, are generated by vibrating structures (e.g. vocal cords) and pressure waves can generate vibration of structures (e.g. ear drum). Hence, when trying to reduce noise it is often a problem in trying to reduce vibration.

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples include a swinging pendulum and AC power. The term vibration is sometimes used more narrowly to mean a mechanical oscillation but sometimes is used to be synonymous with "oscillation." Oscillations occur not only in physical systems but also in biological systems and in human society.

NOT MUCH DIFFERENCE...

WE CALL OSCILLATORY MOTION AS THE VIBRATORY MOTION WHEN THE FREQUENCY IS MORE.....
SO ALL THE VIBRATORY MOTIONS ARE OSCILLATORY..
