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.
Insufficient information for anyone to answer it.
If you push with one newton of force and keep it up through a distance of one meter,then you've expended one joule of energy. It doesn't matter what you're pushing, orwhat its mass is.
