Who Can Solve This Simple Problem? by Nobody: 11:16pm On Oct 10, 2015
if we have an empty measuring cylinder. of mass M, radius r and height H placed on a table, and a fluid/liquid of density P is poured into it,
at what height will the fluid be at when the cylinder is most stable?

in other words,

how high does the fluid have to go in the cylinder for the center of gravity of the whole apparatus to be at it's lowest?


just another problem to think about. smiley

Mg+pie r^2H+p=0 Mg+22/7r^2H+p=0 7mg+22r^2H+7p=0 22r^2H=-7p-7mg H=-7(p+g)/22r^2.

Deboxoxo:
Mg+pie r^2H+p=0
Mg+22/7r^2H+p=0
7mg+22r^2H+7p=0
22r^2H=-7p-7mg
H=-7(p+g)/22r^2.
the result is negative . . . how can one have a negative height?
