Hej Guys, I am just wondering. See the picture. If I put 5kg on the right the water lever increases and the new water level on the left should be as much higher as 5kg volume of water. Its so obvious isn't it? So if it is obvious can you please tell me that why it is possible that in a exactly the same - http://hyperphysics.phy-astr.gsu.edu/hbase/pasc.html#hpress - diagram they hold a car with a fraction of the weight of a car on the left side? I cant understand it how it would be possible... Thanks!
