فهرست واژگان سطح C2 - Engineering

an electronic device that uses a small electrical current to control a larger current, acting like an automatic switch

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

a type of nuclear reactor that generates more fissile material than it often consumes

an environment that can be used to verify the correctness of a model or design

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

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

a thorough inspection and repair of a machine or system to improve its performance or extend 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 that rotates a workpiece so one can shape it by cutting, sanding, or drilling

a professional who uses specialized software to create detailed drawings and plans for buildings, machines, or products

a rotational force measured in newton-meters or foot-pounds

a permanent fastener with a head on one end and a deformable shaft that forms a second head when joining materials together

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

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

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

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