VIBRATION
WHAT IS VIBRATION?A vibration is the motion of the object that are moving back and forth of an object passing through a balance position . The oscillating motion is called a Vibration
EXAMPLES OF VIBRATION MOTION:
these are the common examples of vibration such as the following:
1. Vibration of a pendulum
A swinging Pendulum |
2. Vibration of a plastic ruler
a plastic ruler making a vibration |
3. Vibration of a spring
a spring makes vibration |
CALCULATION OF VIBRATION / HOW TO KNOW THE MOTION OF VIBRATION
a swinging pendulum |
Vibration is calculated by how many times the object moves back and forth. For Example:
The motion is : 1 - 2 -3 - 2 - 1
*A motion of one vibration is always 4 counts, and we do not count the first one as it is the original position of the object and where the vibration starts from.*
OTHER EXAMPLE OF VIBRATION MOTIONS:
a vibration of...........
1/2: 1 - 2 - 3
1/4: 1 - 2
3/4: 1 - 2 - 3 - 2
