21. Like any other vibrating string , these may create nodes and antinodes and greatly influence the predominant frequencies of vibration. 22. The resemblance between the shape of a vibrating string and the graph of the sine function is no mere coincidence. 23. The next in size was called " s�zi ", which had approximately the same vibrating string length as a bouzouki. 24. *PM : vibrating string with variable density, id = 9826 new !-- WP guess : vibrating string with variable density-- Status: 25. The resonant properties of the sound board and the interior of the instrument greatly increase the loudness of the vibrating strings . 26. *PM : vibrating string with variable density, id = 9826 new !-- WP guess : vibrating string with variable density-- Status: 27. For example, an idealized vibrating string can be modelled as the graph of a function on the unit interval, with fixed ends. 28. When fully assembled, each string sits astride a saddle and the saddle thus " marks " the end of the vibrating string . 29. :: I think string theory holds the vibrating strings in question .-- talk ) 11 : 28, 27 March 2010 ( UTC) 30. Tension may also be inferred from the frequency of vibration of the material under stress by solving the " Vibrating String Equation ".
