Engineering

a branch of electronics that deals with the design and manufacture of extremely small electronic components and circuits, typically using semiconductor materials such as silicon

The field of microelectronics has revolutionized the design and production of compact electronic devices.

to pass on information or messages from one place or person to another

The receptionist relayed the important message to the manager as soon as it came in.

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

The bicycle's smooth operation is attributed to the ball bearings in its wheel hubs and bottom bracket.

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

The old factory machines relied on a belt drive system to transfer power from the central engine to various workstations.

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

The engineers used a test bench to evaluate the performance and durability of the new engine 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

The cog in the gear system meshed perfectly with its neighboring cogs, ensuring smooth and efficient power transmission.

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

The engineer used a crank to manually adjust the height of the lifting mechanism.

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

The driveshaft in the car transfers power from the engine to the rear wheels, enabling forward motion.

a set of mechanical parts or devices that transmit and control power or motion in a machine or vehicle

to examine, repair, and make significant improvements or changes to something

The company decided to overhaul its outdated website, introducing a new design and features.

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

The aircraft's fuselage was assembled using thousands of rivets to ensure a strong and durable connection between the metal panels.

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

The bicycle's rear wheel is connected to the chain and sprocket assembly, facilitating smooth pedaling.

a machine tool that rotates a workpiece so one can shape it by cutting, sanding, or drilling

The machinist used a lathe to shape the metal rod into a precise cylindrical form.

the earth's atmosphere and the space beyond it

She studied aerospace engineering to pursue a career in space exploration.

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

A computer-aided design technician plays a crucial role in translating conceptual ideas into precise digital blueprints for manufacturing.

the branch of mechanics that studies the motion of objects without considering the forces that cause the motion

In physics class, students often study the kinematics of projectile motion to understand the trajectory of objects.

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

The wrench applied torque to loosen the stubborn nut on the bolt.
