Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...

Two piano strings have the same length (0.7 cm) and mass density
(16 grams/meter), but the tension of one string is 6% greater than
the first. If beats with a frequency of 5 Hz are observed when the
third (n=3) harmonics of each string are excited simultaneously,
what is the tension of the string with the lower pitch (frequency)?
Answer in newtons to the nearest newton.

In certain ranges of a piano keyboard, more than one string is tuned to the same note to provide extra loudness. For example, the note at 110 Hz has two strings at this frequency. If one string slips from its normal tension of 610 N to 530 N, what beat frequency is heard when the hammer strikes the two strings simultaneously? beats/s

6. Two identical speakers are emitting sound of the same frequency. Speaker 1, located 5 m away, has a sound level of 76 dB. Speaker 2, located 10 m from you, has a sound level of 73 dB. Assuming spherically radiating sound waves, which of the two speakers is producing the sound at higher power? 7a.

Guy wires used to support tall radio antennae often need to be kept at a specific...
Guy wires used to support tall radio antennae often need to be kept at a specific tension or else the antennae may bend or buckle. The tension tends to decrease over time as the wire ages (and stretches) but on cold days, when the wire contracts, the tension increases. So, to keep the tension within tolerances, the tension in the wire is checked regularly and adjusted if it is found to be outside of tolerances. One way to check the...
