Homework Statement
Find the equilibrium separation between Diamond and Copper materials.
Homework Equations
Lennard-Jones force/unit area:
[itex]p_a(z)=\frac{8w}{3z_0}\left[\left(\frac{z}{z_0}\right)^{-9}-\left(\frac{z}{z_0}\right)^{-3}\right][/itex]
I need to find [itex]z_0[/itex] which is the equilibrium separation.
w is the surface adhesion energy in Joules/m^2.
The Attempt at a Solution
I did not know where to post this question because I do not know if it even has a solution with the information that I have. It is a question I am asking myself because I am trying to predict some behavior to purchase some things. I know that equilibrium separation is where there is zero force/stress encountered. However, I do not know where actual data for equilibrium separation is obtained. Must it be done experimentally? Is it something non-trivial?
Is this the right board to post this in? Should this be in physics, or elsewhere?
