1. The problem statement, all variables and given/known data Why does a log float horizontally as opposed to vertically? 2. Relevant equations Nah 3. The attempt at a solution I can kind of imagine why a vertical log would be in unstable equilibrium, but the thought isn't quite as logically cohesive as I'm comfortable with, so could anyone elaborate using concepts of buoyancy or even energy (which I think does have something to do with it) Taken from the "questions" section of Halliday and resnick, chapter 17: fluid statics.
