SUMMARY
The discussion centers on Pascal's Law and its application to a symmetrical container with four pistons, each exerting force F on the fluid. The key conclusion is that the increase in pressure at the center of the container is F/A, not 4F/A, because pressure is defined as the perpendicular force per unit area applied to a fluid. This highlights that pressure is an intensive variable, independent of the size of the system, and is treated as a scalar quantity, which resolves the confusion regarding vector forces.
