quantum chromodynamics - What are the equations for the weak and strong forces?

What are the equations for the strong and weak force, like how for the Electrostatics the equation is $F_c= k*Q*q/(r*r)$. I understand to an extend what the strong and weak forces are. However, I would like to know what the equations for calculating the forces. Also can you explain how the equations works and define the variables.

I understand that they may not be as simple and as pretty and the electrostatic one.
