(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Longnitudal and transverse soundwaves in nickel (FCC lattice) moves at velocities 5300m/s 3800m/s. Determine the elastic constants C_{ijkl}

2. Relevant equations

[tex]v =\sqrt{C_{ij}/\rho}[/tex]

3. The attempt at a solution

I guess I can calculate C_{ij}with that equation....but I dont understand how I get the indices ij, or ijkl...And I dont understand how am I supposed to use the longnitudal AND transverse wave speeds....
