Web26 de fev. de 2024 · Sorted by: 2. Pressre in a fluid at a point has the same magnitude in every direction. If the "pressure" was different in two perpendicular directions, then there would be a shear force acting on the fluid in directions in between those two. A fluid can not support shear stresses, by definition - that is the difference between a fluid and a solid. Web3 de dez. de 2015 · $\begingroup$ @Brionius I was using some hydrostatic simplifications which state that the horizontal component of the force on a sample area is the pressure at the center of the area times the area, and the vertical component is related to the volume of fluid above the projected area, which is zero in this case for a cylinder.
