BIENT PRESSURE: Can Vacuum Pressure be Multiplied?

[Idea04]

Homework Statement

I know with hydraulic multiplication a small piston can create an increased force upward on a large piston. But if you take the small piston and pull upward on it creating a vacuum. Would the large piston have a multiplied vacuum force pulling it downward.

Perhaps you could explain the configuration you have in mind. If you pull on a hydraulic cylinder, you will push fluid out in front and draw hydraulic fluid in on the back side.

I'm wondering if vacuum pressure can be multiplied in the same way fluid pressure can be multiplied.

No. Vacuum is the absence of pressure. There is a pressure limit for a vaccum: zero. So the greatest net pressure you can create by creating a vacuum is the ambient pressure.
