Re: [Phys-l] buoyancy on a submerged pole - withdraw



The density of a box whose under surface is impenetrable by fluid is immaterial

But *what* removed the buoyant force? I think there wasn't one to start with,

Do you agree that the flat bottom flexes differently when the box is
glued to it than when there is no box glued to it?

If you don't accept this effect then you're right - there is/was no
buoyant force.

I'm claiming (personally) that an experiment will show an upward
force acting on the bottom of the aquarium when the box is glued to
it.

Let the measurements begin?!?!?!
It's as well to mention that you are visualizing a box whose density
is less than the water in which it is submerged.
