What type of power leverages the movement of liquids to transmit force?

Hydraulic power is the correct answer because it utilizes the principles of fluid mechanics to transmit force through liquids. In a hydraulic system, pressurized fluid is used to create movement and lift objects, making this type of power particularly effective for applications that require significant force over a distance. The incompressibility of liquids allows for efficient force transmission, enabling hydraulic machines to operate heavy machinery such as excavators, lifts, and brakes with relatively little effort from the operator.

In contrast, pneumatic power relies on compressed air to transmit force, while mechanical power involves the direct application of mechanical systems like gears and levers. Electrical power involves the use of electrical energy to perform work, which is distinct from the force transmission characteristics of fluids in hydraulic systems. Each of these other forms of power has its own applications and principles, but they do not specifically harness the movement of liquids in the same effective manner as hydraulic power does.
