Basic physics questions.....
Since a bunch of you actually went to college (or maybe paid attention in high school), I have a few questions hopefully some of you can answer before I attempt to post them elsewhere, and have people suggest I'm trying to get them to do my homework.
The picture is supposed to resemble a sealed cylinder divided into two separate chambers (A & B) by a floating piston in between.
Not accounting for friction, or gravity, or any other factors than what I state, I ask:
1. Chamber B is filled with air @ 10 psi, while chamber A is at 0 psi. If the surface area of the piston facing the chambers is 10sq inches - is the total force applied to the B-side of the piston 10 psi, 100 psi, or neither?
2. Using the same example, lets say that instead of chamber A being at 0 psi, it is at 5 psi. Does that mean the total force on the b-side of the piston is now half of what it was when chamber A was at 0 psi?
