COEFFICIENT OF THERMAL EXPANSION DETERMINATION METHOD USING FUNDAMENTAL FREQUENCY OF THE STRING

Popis výsledku v původním jazyce

The coefficient of thermal expansion of guitar string material was obtained by its fundamental frequency measurement. Principle of the method is tension change caused by temperature change in statically indeterminate attachment of the string which results in change of its vibration fundamental frequency. The method is very simple and has better advantage compared to other possible methods of determining the coefficient of thermal expansion. Especially the need for advanced laboratory equipment. Such aspush-rod dilatometer (Vikram et al., 1986), laser interferometric dilatometer (Okaji et al., 1997), capacitive dilatometer (Abe et al., 2012) and more (Kanagaraj, Pattanayak, 2003). Introduced method requires thermometer, frequency measuring device suchas digital musical instrument tuner, rigid base for string attachment and different temperature environment provider such as fridge or oven. Steel electric guitar strings were used for method verification.
