Which term is a device that converts mechanical force into hydraulic fluid power?

• A. Psi
• B. Hydraulic pump
• C. Coil inductor
• D. Hydraulic cavitation

Answer: (B)

In a hydraulic system, converting mechanical energy into hydraulic fluid power is done by a hydraulic pump. It takes energy from a motor or engine and moves hydraulic fluid, creating flow and increasing pressure so that force can be transmitted through the fluid to power cylinders, motors, or other components. The hydraulic power produced is essentially the combination of pressure and flow the pump creates. Psi is just a unit of pressure, not a device. A coil inductor is an electrical component that stores energy in a magnetic field, not hydraulic energy. Hydraulic cavitation is a flow-related phenomenon where vapor bubbles form under low pressure, not a device that converts energy.
