Imagine that there's a force that is given to you in $psi$, say $1450\ psi$. And there's some body of weight say, $100\ kg$.
What I want to know is that, how much $psi$ will I need to lift the "body" above the ground? Is there any formula to calculate the same?
Moreover, I'd like to know that how much $kg$ can $1450\ psi$ lift above the ground?
