Sorry, I evidently turned underline on when making that second equation. Here is is again.
If u = z' and u'' = z'' (or u du/dz = z''), then u(du/dz) + a[ u ]^2 + b[ z ] = c
Hello,
I'm a doctoral student in civil engineering. In my research I came across a differential equation for the net force acting on an object as it impacts a granular medium at low velocities.
z'' + a[ z' ]^2 + b[ z ] = c
Where a, b, and c are all constants
I believe that this equation will...
