the musical instrument such as a piano may be tuned by using the phenomenon of beats.
The phenomena of beat frequency is often used to tune musical instruments like piano. A tuning fork is tapped ad a string of paino is plucked simultaneously. If the two sound sources produce beats whose frequencies are different, their frequencies won't be identical, and they are will out of tune and noise. Hence the above process is repeated until the frequencies are identical and resonant and the frequencies are not distinguished. Thus making the instrument in tune
This method will work more efficiently for an instrument that is entirely out of tune because it will be easier to distinguish the beats of the instruments and the tuning fork.
Hence the musical instrument such as a piano may be tuned by using the phenomenon of beats.
Applying the summation of torques about the wedge for equilibrium, taking the clockwise direction as negative. Since the ruler is balanced horizontally about the wedge. Therefore, the summation of all torques acting about the wedge must be equal to zero.
