👉 The fluid force, also known as pressure or stress in a fluid context, refers to the force exerted by a fluid per unit area. When a fluid like water or air is subjected to an external force, it transmits that force equally in all directions across its surface, resulting in a pressure distribution. This pressure is a measure of the force per unit area and can vary significantly depending on the fluid's density, the force applied, and the area over which the force is distributed. In essence, fluid forces are crucial in understanding phenomena such as buoyancy, fluid flow dynamics, and the behavior of hydraulic systems.
