What is the term used to describe the use of liquids to transfer force?

The term used to describe the use of liquids to transfer force is hydraulics. This process relies on the principles of fluid mechanics, allowing for the efficient transmission of power through incompressible fluids, typically oils or water. In hydraulic systems, force applied at one point is transferred through the liquid to generate movement or exert pressure at another point. This method is commonly utilized in various applications, including machinery, automotive systems, and construction equipment, due to its capacity to generate significant force in a compact form.

Pneumatics, in contrast, involves the use of gas to transfer force, while mechanics is a broader term encompassing the study of motion and forces but does not specifically reference the transfer of force through liquids. Kinetics focuses on the forces and motions of objects rather than the transfer methods themselves. Hence, hydraulics is the most accurate term for the transfer of force using liquids.
