Abstract

The research has been conducted to determine the Young Modulus value of the fishing line with frequency analysis on a string by using a sound sensor. The fishing line made of Nylon Monofilament and Stainless Steel Nylon Coat. The diameter of the fishing line with each material consisted of 0.25 mm. The fishing line vibration events ware displayed on the graph of the relationship between pressure and time in the Logger pro program. The graph of the relationship between pressure and time was then transformed into an FFT graph of the amplitude relationship to frequency. Then the frequency value which was obtained from the FFT was used to determine the wave velocity value of the fishing line. The average wave velocity value was obtained by graphing the frequency relation to one of each string length. After obtained the average wave velocity value of the fishing line the Modulus Young value can be determined by the equation of the square wave velocity relationship times the mass per length times the cross-sectional area. In this study, the Young Modulus value of Nylon Monofilament fishing line was (1.94±0.09) GPa and the Young Modulus value of the Stainless Steel Nylon Coat fishing line was (45.05±2.05) GPa.

用弦频率分析方法测量杨弦弦

研究人员利用声音传感器对一根串进行频率分析，以确定钓鱼线的杨氏模量值。该钓线由尼龙单丝和不锈钢尼龙涂层制成。每种材料的钓线直径为0.25毫米。在Logger pro程序中，钓鱼线振动事件显示在压力与时间关系的图形上。然后将压力与时间的关系图转换为振幅与频率关系的FFT图。然后利用FFT得到的频率值来确定钓鱼线的波速值。平均波速值是通过绘制频率与各弦长之间的关系得到的。在得到钓鱼线的平均波速值后，模数杨氏值可由方波速度关系乘以每长度质量乘以截面积的方程确定。在本研究中，尼龙单丝鱼线的杨模量值为(1.94±0.09)GPa，不锈钢尼龙涂层鱼线的杨模量值为(45.05±2.05)GPa。
