Hydrostatics

Definition

Hydrostatics is the branch of physics that studies fluids at rest, focusing on the forces and conditions exerted by fluids when they are not in motion. This area of study was crucial in understanding buoyancy, pressure, and how fluids behave in various situations, influencing technology and engineering in the Hellenistic period. The principles of hydrostatics contributed to advancements in water management, construction, and mechanical devices during this time.
