Hi, I had a question regarding pressure and suction.
Say you have 2 walls with a suction cup that is attached to each.
Initial volume of the cup is 1m^3, area attached is 1m^2
Initial pressure is 1 atm
Both walls have a hole of different sizes with a pipe leading out to atmosphere.
1 pipe...
If a cube submerged in water is attached to the floor with a telescopic cylinder taking up part of the surface area on the bottom of the cube, will the buoyant upward force be a fraction of the surface area on the bottom of the cube exposed to water, or will the full buoyancy effect take place...
