What is meant by fluid power in engineering?

Fluid power in engineering specifically refers to the use of hydraulic or pneumatic systems to transmit power through fluid. This involves either liquids (hydraulics) or gases (pneumatics) that can be harnessed to exert force and perform work effectively. Fluid power systems can generate high levels of force using relatively small amounts of fluid, allowing for efficient energy transfer and control in various applications, including machinery, robotics, and automotive systems.

The correct answer highlights this crucial aspect of using a fluid medium to move energy and force from one part of a system to another, which is fundamental in many engineering applications. This method of power transmission is advantageous because it allows for smooth operation, precise control, and the capability to transmit power over long distances without significant losses.
