![]() ![]() Also, explain about resonance and frequency and differentiate between them by giving an example for each of the phenomena. Note: Here, first explain about tuning fork, give a brief about its purpose and its construction. When a vibrating tuning fork is placed on a table, a large sound is heard. ![]() Similarly, a good example of a forced vibration is when we put an already vibrating tuning fork on the table and we hear a large sound.įinal answer is option A. Vibrations are created in the second tuning fork B due to resonance. The tuning fork is excited to its resonant frequency by piezoelectric material. When you shake the tuning fork A, the other tuning fork B begins to vibrate as well. Here, a good example of resonance is when we bang the tuning fork on the table and bring it closer to our ear the air around the fork starts to vibrate and then we can hear the sound. A piezoelectric motor vibrates two metal protrusions, referred to as a tuning fork. Resonance is a phenomenon in which a vibrating system forces another system which is around it to vibrate with greater amplitude at a given frequency whereas a forced vibration is a phenomenon in which an alternating force or motion of an object or a system is applied to a system of a mechanical nature, in forced vibration the force is repeatedly applied to a mechanical system. A resonator is a device which oscillates naturally at greater amplitudes at a given frequency, these frequencies are called resonant frequencies. It is a type of resonator and unlike other resonators it gives out a pure sound. In this paper, a piezoelectric nanogenerator (PENG) based on a tuning fork-shaped cantilever was designed and fabricated, aiming at harvesting low frequency. It is a U-shaped device that is made up of metal. Tuning fork as the name suggests is a device that is used for tuning musical instruments. The tuning fork is soundless when it is in an ideal state and we bang the tuning fork on the table or on any solid surface and bring the tuning fork closer to our ear when we hear a sound. THE tuning-fork when its number of double vibrations, to and from in a second, or briefly its frequency, has been ascertained, is a most convenient. Hint: Sound happens when there is a to and fro motion of an object, when an object oscillates on its own then the sound happens. ![]()
