In this problem we have a tank filled with
an incompressible fluid.
It is open to the atmosphere so we designate
it as such.
And we have a block that is initially floating
on the surface.
And we have designated this as state 1.
Now we add a little bit of mass on top of
this block.
And by adding this mass we cause the block
to sink a little bit to a new state 2.
So we add a little bit more mass, same amount
that we added before.
Which causes the block to move down to another
state, state 3.
We do this another time, adding the same incremental
mass that we did before, which gives us a
new state, state 4- In which the block is
completely submerged under water, but the
weight is still floating at the top.
So the question is, if I add just a little
bit more mass, same amount of mass that we
have added at every incremental step, but
I do it one more time so that we added just
a little bit more mass, where do we expect
state 5 to be?
Do we expect that state 5 will be at position
A, in which the block sinks linearly as the
other ones did.
Do we think it will be block B in which it
hovers somewhere in the middle of this fluid.
Or do we think it will be block C in which
it sinks to the bottom.
Click on whatever block best represents what
you think is going to happen next if we add
just little bit more mass.
