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

So your conclusion is that strain gauges attached appropriately will show compression as the pole is submerged,

I'm not from Missouri - but I DO look forward to some experimental results.

I'm guessing that the lightweight pole would indeed stretch upward a
bit as it becomes submerged.

Did you look at my solutions to the submerged pole problem (assummed
impermeable). See:
<http://www.anselm.edu/internet/physics/phys-l/pilingProb.pdf>
I solved it using your definition of buoyancy and again using the net
force of the fluid viewpoint. One gets the same answer either way. The
pole is in compression.
