The speed of longitudinal wave is 100 times the speed of transverse wave in a brass wire. What is the stress in the wire? The Young modulus of brass is $1.0 \times 1 0^{11}$ N/m².

Answer:

10000000

Solution:

$v_{l} = Y / ρ$ and $v_{t} = T / μ = σ / ρ$ where $σ$ is the stress. $v_{l} / v_{t} = 100$ gives $σ = Y /1 0^{4} = 1 0^{7}$ N/m².
