- I will post below.

First i will use a equation resulted in considering a spring as a continuum limit of massive mass:

ω = √(KL/ρ)*kn

ρ is the linear density ρ

ω = √(KL/ρ)*kn

X = A*cos(kn*x)*cos(ω*t)

**ξ = A (first consequence)**

X = ξ*cos(kn*x)*cos(ω*t)

*∂y/∂x need to be zero in x=L (for strain be zero)*

**kn*L = n*π (second)**

ω = √(KL/ρ)*kn = √(KL/ρ)*n*π/L

So

X = L + ξ*cos(((n*π))*cos(ω*t)

where

ω = √(K/M)*n*π

n is a natural

This seems okay?
