A piano string 1.5 m long is made of steel of density 7800 kg/m^3 and young's modulus 2x10^-11 N/m^2. It is maintained at a tension that produced an elastic strain of 1% in the string. Calculate the frequency of transverse vibration of the string when it is vibrating in the second mode of vibration.
State the laws of transverse vibrations of string. Using only dimensions show that the speed of propagation of transverse wave depends only on tension and mass per unit length.
State the laws of transverse vibration in a stretched string. Describe various modes of vibration in a stretched string.
