This is a kind of trick question.
In a closed static system containing fluid, pressure is equal everywhere. This is called the Law of Pascal.
One can use this principle to lift a car with a finger. Fill a tank with water and have a car float on a platform. Now make a hole in the tank and connect a tube to it. By preventing the tube to leak, you have to apply a certain pressure, which may be smaller than 1 bar. If you increase the pressure, either by hand or possibly by blowing the tube, you can lift the car. Not so much with a short tube, but more with a long tube. The higher pressure in the tube will push the water back in the tank and cause the water in the tank to rise with the car on top of it.

Bar is a unit used to measure pressure, one bar is the normal atmospheric pressure of the on the surface of the earth, and ten bar is when the pressure is ten times the normal atmospheric pressure on the surface of the earth.
how many steel bar in one ton
Assuming you need a metric ton, that's 1000 kilograms. To lift that, you need a FORCE of 9800 newtons. Force is related to pressure by: pressure = force / area, so the answer to the original question would depend, over what area the force is applied.
carnage can lift 50tons and 2tons is the strength of a car so just imagin how many cars carnage could lift in one hand carnage can lift 50tones and venom can lift 80tons so imagin how many cars venom and carnage could lift in one hand
It really depends on how big the bar is, but usually one troy ounce.
