Force, Pressure and Area.  The force acting on a certain area is called pressure  If you change the area but keep the force the same the pressure changes.

General idea:  The column of air exerts a force on the surface of the earth.  This force per area is as large as 1.03x10 5 Pa at sea level, also known.

CE 230-Engineering Fluid Mechanics Lecture # 6 Basics of Fluid Statics

What can we say about the pressure at a point in a static fluid? Consider equilibrium of the shown element

Conclusion Only normal forces exist in static fluid Pressure at a point in a static fluid is independent of direction

Pressure variation in a static fluid

Relation between gage and absolute pressure

Pressure transmission and hydraulic lift

Example 3.1 What load F2 can the hydraulic jack support if one exerts a force F = 100 N? Neglect weights.
