CEFR C2 Vocabulary - Engineering

an electrical device that typically contains an electromagnet, which is activated in response to a signal or current in one circuit to close or open another circuit

a type of rolling-element bearing that uses balls to maintain the separation between the bearing races, reducing friction and enabling smooth rotation

a mechanical transmission system using a flexible belt to transfer power between rotating shafts

an evaluation of a component or system's performance, often outside of its operational context, typically conducted in a controlled environment

a wheel with a set of square or triangular teeth sticking out around the edge that fits into the edge of a similar wheel, causing both wheels to turn

a device that allows movement between mechanical parts of a machine or converts backward and forward motion into circular movement

a mechanical component that transmits rotational power from the engine to the wheels or other driven components of a vehicle or machine

the arrangement of gears, toothed wheels, or mechanical components designed to transmit and control power between rotating shafts in a machine, vehicle, or system

a comprehensive examination, repair, and restoration of a machine, system, or structure, usually with the goal of improving its performance, efficiency, or extending its lifespan

a toothed wheel with projections that mesh with a chain, track, or other perforated or indented material, typically used to transmit motion or power in machinery, vehicles, or bicycles

a machine tool used in woodworking, metalworking, and other industries to rotate a workpiece on its axis while cutting, shaping, or drilling it with various tools to create symmetrical objects such as cylindrical or tapered parts

a professional who uses specialized software to create detailed technical drawings, 2D and 3D models, and digital representations of designs for various industries such as architecture, engineering, manufacturing, or construction

rotational force measured in newton-meters or foot-pounds

the capability of being easily changed or molded into many different things

a permanent fastener consisting of a cylindrical shaft with a head on one end, used to join or secure two or more materials together by deforming the end of the shaft to form a second head

a method used to extract natural gas or oil from deep underground by injecting high-pressure fluid to fracture rock formations

an electric device that is used to increase or decrease the voltage of an alternating current

facility that transforms voltage levels and regulates electrical currents, typically situated in an electrical power distribution system

a chemical reaction between a fuel and an oxidizing agent, typically producing heat and light

a type of nuclear reactor that produces more fissile material than it consumes, using fast neutrons

a pipe, tube, or channel that is used to protect, enclose, or route electrical wires, cables, or other utilities for the purpose of safe and organized transmission

an electric current that reverses direction periodically, typically used in power distribution systems due to its efficiency in long-distance transmission

a type of fuel made from living matter, such as plants or waste, that can be used as a renewable energy source

a gas, especially methane, that is produced as a result of the decomposition of animal or plant remains, which is used as fuel

relating to systems or devices that involve both electrical and mechanical components or functions
