Question
A sonometer wire of length 1.5 m is made of steel. The tension in it produces an elastic strain of 1%. What is the fundamental frequency of steel if density and elasticity of steel are 7.7 × 103 kg/m3 and 2.2 × 011 N/m2 respectively ?
Options
A.188.5 Hz
B.178.2 Hz
C.200.5 Hz
D.770 Hz
Solution
Fundamental frequency 
(S → cross - section Area)
= 178.2Hz
(S → cross - section Area)
= 178.2HzCreate a free account to view solution
