Definition

Adjective 1. Having a common axis: Describes two or more objects, typically geometric figures like circles, cylinders, or cables, that share the same central line or axis of symmetry.

Usage and Examples

• The signal is transmitted through a coaxial cable, which consists of a central conductor surrounded by an insulating layer and a tubular conducting shield.
• In geometry, coaxial circles are circles whose centers all lie on a single straight line.
• The new antenna design uses coaxial feed lines for improved performance.

Advanced Usage

• Coaxiality (noun): The state or condition of being coaxial. This is a technical term used in engineering and geometry to describe precision alignment.
  • The machinist measured the coaxiality of the two bores to ensure they were perfectly aligned.
• Coaxially (adverb): In a coaxial manner; arranged along a common axis.
  • The components are mounted coaxially within the assembly.

Variants and Related Words

• Coaxal (adjective): A less common variant with the same meaning as coaxial.
• Coaxial Cable (noun): A specific type of electrical cable with a coaxial structure, widely used for transmitting radio frequency signals, cable television, and internet data.

Synonyms

• Concentric: This is a close synonym but has a specific nuance. While all coaxial circles are concentric, not all coaxial objects are concentric. "Concentric" strictly implies sharing the same center point, whereas "coaxial" implies sharing the same axis line, which is a broader condition.
  • Example: Two cylinders can be coaxial (share the same central line) but not concentric if they have different diameters and are offset along that line.

Technical and Compound Terms

• Coaxial Connector: A type of electrical connector designed to maintain the coaxial shielding of a cable, such as an RCA, BNC, or F-type connector.
• Coaxial Rotor: A helicopter rotor system where two sets of rotor blades are mounted on the same axis, one above the other, rotating in opposite directions.
