Chapter 12, Problem 14RQ

Give three examples of forced vibration.

Solution

To determine:

Three examples of forced vibration.

Answer:

A struck tuning fork held against a table, vibration of a car moving through road and vibration of water in a bucket due to vibration of floor are the three examples of forced vibrations.

Explanation:

If an object vibrating at a particular frequency sets vibrations in another object, it is called forced vibrations.

A struck tuning fork held against a table causes vibrations in the table. It is an example of a forced vibration because the table was forced to vibrate by the tuning fork. The vibration of a car moving through a road with gutters is forced vibration.

A bucket with water is kept on a floor. When an object having a huge mass is dropped into the floor, the water surface is observed to vibrate. The vibrations occur on the floor due to the object caused vibrations in the water. So, it is also an example of forced vibration.

Conclusion:

Therefore, a struck tuning fork held against a table, vibration of a car moving through road and vibration of water in a bucket due to vibration of floor are the three examples of forced vibrations.
