Solve the following question given below:
A steel guitar string is stretched between two fixed supports 88.1 cm apart. When the temperature is 0 °C, the fundamental frequency of transverse oscillations of the string is 189 Hz.
1- What will be the value of fundamental frequency in Hz if the temperature is raised to 45.1 °C? Useful Data: mass density of steel is: 8.09 x 103 kg/m3 Young's modulus of steel is 1.93 x 1011 N/m2 Coefficient of thermal expansion of steel is 18.1 x 10-6 /K.
