How much psi does it take to lift 1000 lbs?

Answer 1

The question can't be answered as asked. PSI (pounds per square inch) is a measure of pressure (or force) over a given surface area, but without knowing the surface area in question, the psi can't be calculated. However, it might help to understand it better by considering that a 1000 pound weight that is spread evenly over a surface area of 1000 square inches will only have a psi of 1. On the other hand, if you take that same 1000 pound weight and put it on a hand truck with two wheels, each wheel having a surface area (the area of wheel in contact with the ground) of 4 square inches, the area beneath each wheel will have a force (or pressure) of 125 psi being placed on it. Hope that helps.

Answer 2

There is no fixed relationship, or rather consider a piston of 2000 square inches; then 1 PSI would lift it. If the piston had a larger area, then even less would be needed. If the piston had 1 square inch, then 2000 PSI would do it.

Answer 3

It depends upon the cross sectional area of the lift cylinder. With a cross sectional area of 1 square inch, it would take 1000 psi. However, increase the cross sectional area to 10 square inches, and it would take only 100 psi.

Answer 4

Depending on the cross sectional area there it may take around 100 psi. However, this will depend on the how large the cross sectional area is.
