1. The problem statement, all variables and given/known data Does that container full of water gives a torque on Earth ? http://imageshack.com/a/img537/6733/9Y0Hqq.png [Broken] 2. Relevant equations -- 3. The attempt at a solution I drawn all interesting forces : http://imageshack.com/a/img540/9315/ymwwvW.png [Broken] Like that there is a torque from F2-F3, but it's strange, then I think I'm wrong, F2 and F3 have a direction to the center of the Earth ?
