FORCED VIBRATIONS Meaning and
Definition
-
Forced vibrations refer to oscillations or vibrations that occur in a system due to the application of an external force or input of energy. In this context, a system could refer to any physical object or structure that is capable of vibrating, such as a guitar string, a pendulum, or a membrane.
This external force could be periodic or non-periodic, and is typically imposed on the system continuously or periodically. When the natural frequency of the system matches the frequency of the external force, resonance occurs, resulting in significantly amplified vibrations.
The concept of forced vibrations can be better understood by considering an example of a swinging pendulum. If the pendulum is subjected to a constant external force, such as a person pushing the pendulum at regular intervals, the pendulum will exhibit forced vibrations. The frequency of the force applied by the person corresponds to the natural frequency of the pendulum, thereby causing resonance and amplifying the oscillations.
Forced vibrations are commonly observed in various technological applications, such as musical instruments. For instance, when a guitar string is plucked, the force exerted by the player's fingers causes the string to vibrate, generating sound. Additionally, forced vibrations can occur in structures subjected to external forces, such as bridges or buildings experiencing resonance due to wind or earthquakes.
Understanding forced vibrations is crucial in various scientific and engineering fields, as it helps in analyzing and predicting the behavior of systems under external forces, allowing for the design and optimization of structures, machinery, and instruments.

Etymology of FORCED VIBRATIONS
The etymology of the word "forced" can be traced back to the Latin word "fortis", meaning "strong" or "powerful". This Latin term eventually evolved into the Old French word "forcier", which meant "to constrain" or "to compel". The English word "forced" emerged around the 13th century, carrying the meaning of "compelled" or "not occurring naturally".
The word "vibration" has its roots in the Latin verb "vibrare", which means "to shake" or "to sway". From "vibrare", the Latin noun "vibratio" was formed, denoting a vibrating or shaking motion. Over time, this word made its way into Middle English as "vibracioun", then eventually transformed into the modern English word "vibration".
