Class Vocabulary

Vocabulary TermDefinition
actuator Components that directly help convert hydraulic or pneumatic energy into mechanical energy.
closed-loop system A type of fluid power system that uses feedback to maintain consistent input and output. Closed-loop systems are also called servo systems.
cylinder A type of linear actuator that uses a piston to produce motion in a straight line. A cylinder is also known as a piston actuator.
drag The resistance to flow. Drag is used to describe friction of air.
efficiency The amount of power output by a fluid power system compared to the amount of power input.
energy The ability to perform work.
feedback transducer A device that monitors input and output signals in a closed-loop fluid power system.
first law of motion A scientific law of inertia developed by Sir. Isaac Newton. Newton's first law of motion states that an object will remain at rest or in its original motion until acted upon by an outside force.
fluid conductor The component such as a pipe, tube, and hose that conveys liquids throughout a hydraulic or pneumatic system.
fluid flow The volume of fluid displaced by a pump or compressor into a hydraulic or pneumatic system.
fluid flow rate The volume of fluid displaced within a given time. Fluid flow rate also determines the speed at which work is performed by fluid power systems.
fluid power system A power transmission system that uses fluids such as oil and air to transmit power. Hydraulic systems and pneumatic systems are types of fluid power systems.
foot-pound The unit used for measuring work. Foot pounds is abbreviated as ft.lbs.
force The push or pull that gives energy to an object.
force multiplication The exponential increase in available power usually associated with tools and power transmission systems.
friction The force that resists motion between two objects.
horsepower The unit used for measuring power.
hydraulic system A power transmission system that uses the force of flowing liquids to transmit power.
inch-pound The unit used for measuring work. Inch pounds is abbreviated as in.lbs.
kinetic energy Energy of motion.
law of conservation of energy The scientific law that states energy can neither be created nor destroyed.
lubricity The property that diminishes friction and increases smoothness and slipperiness.
mechanical energy Energy used to perform work through the physical interaction and motion of instruments or tools.
moment of inertia The tendency of an object in motion to rotate until acted upon by an outside force. The moment of inertia is also known as rotational inertia.
motion A change in an object's position as a result of an the imbalance of forces created by energy transfer.
newtons per square meter A unit of pressure. A newton per square meter is also known as a pascal, which is derived from the International System of Units (SI).
Pascal's Law A hydrostatic principle that states when pressure is applied to a contained fluid, the force is transmitted equally in all directions.
pneumatic system A power transmission system that uses the force of flowing gases to transmit power.
potential energy Stored energy resulting from an object's position or from internal pressure.
pounds per square inch A unit of pressure. Pounds per square inch is derived from the English system of measure and is abbreviated psi.
power The rate of doing work in a specified period of time.
pressure The amount of force applied upon an object. Pressure is a derived unit that combines time, area, and mass.
prime mover The component of a hydraulic or pneumatic system that powers the main pump or compressor.
radius The distance from the center of an object to its periphery.
revolutions per minute The number of times a component rotates 360 degrees, or in a complete circle, in one minute. Revolutions per minute (rpm) is a measurement of speed.
rotational inertia The tendency of an object in motion to rotate until acted upon by an outside force. Rotational inertia is also known as the moment of inertia.
servo system A type of fluid power system that uses feedback to maintain consistent input and output. Servo systems are also called closed-loop systems.
servo valve A valve used to direct fluid to an actuator in a closed-loop or servo system.
static The state of an object at rest.
torque The force that produces rotary motion.
velocity The distance traveled by an object over a specific period of time.
viscosity A fluid's resistance to flow. Viscosity is used to describe friction of fluids.
volume The amount of space that an object occupies. Solids and liquids have definite volume.
work The result of force applied to an object over a distance.
