Question

Find the elastic limit of the wire when the maximum speed of the wave passing through this wire 164 m/s . The density of this wire is 8.96 gkins

Answer 1

Hey Dear,

◆ Answer -

Elastic limit = 2.41×10^8 N/m^2

◆ Explaination -

Velocity of wave passing through wire is calculated by -

v = √(F/μ)

v^2 = F/μ

v^2 = F/(M/l)

v^2 = F/(ρV/l)

v^2 = F/ρA

F/A = ρ.v^2

But we know, F/A = elastic limit,

Elastic limit = ρ.v^2

Elastic limit = 8.96×10^3 × 164^2

Elastic limit = 2.41×10^8 N/m^2

Hope that's helpful...
