Post making contest: easier mode

Once upon a shitpost, there lived a small fucksicle. It was cold, but then the sun melt it and it died the end.

This post passes no rules.

gonna set myself the challenge of finishing this question (and thus the problem sheet) before midnight

good luck, me

This post passes no rules.

if this nasty-looking derivative term I've been hauling around as luggage turns out to be what I think it is then I have indeed managed to show that, for an incompressible isotropic material, a solution to the radial equilibrium equation generates a solution to the 3D equilibrium equations

...now if only I could actually figure out how to work through this awkward term...

This post passes rule 3.

THERE WE GO

strictly speaking I was half an hour behind schedule going into this question so I actually made up eight minutes there

If you ask me, for an incompressible isotropic material, a solution to the radial equilibrium equation generates a solution to YOUR FACE.

This rude post passes no rules.
