elongation

 [e-long-ga´shun]
1. the act or process of increasing in length.
2. a radiographic distortion in which the image is longer than what is being x-rayed.

e·lon·ga·tion

(ē'lon-gā'shŭn),
1. The increase in the gauge length measured after fracture in tension within the gauge length, expressed in percentage of original gauge length.
2. The lengthening of a macromolecule, for example, in the synthesis of long-chain fatty acids or in the synthesis of a protein.

elongation

[i′longā′shən]
Etymology: L, elongatio, a prolonging
a state of being lengthened or extended.

e·lon·ga·tion

(ē-long-gāshŭn)
radiology Radiographic distortion in which the image appears longer than it is; caused by insufficient vertical angulation.

e·lon·ga·tion

(ē-lawng-gāshŭn)
Stretching lengthwise or result of such action.

elongation (ē´lônggā´shən),

n the process or condition of increasing in length before breaking; indicates ductility (e.g., of a metal).
elongation, percent,
n 1. the increase in length of a material after fracture in tension.
n 2. a mechanical test usually employed to measure ductility.

elongation

1. in protein synthesis, cyclic process of growth of a polypeptide chain from mRNA attached to ribosomes. Requires mRNA, ribosomes, activated aminoacyl-tRNA, elongation factor EF-Tu activated with GTP.
2. in fatty acids, a process of adding carbon from acetyl CoA to a lengthening acyl chain. Mechanism for achieving diversity of fatty acids in biological systems.

elongation factor
one in a group of proteins involved in the elongation of polypeptide chains during protein synthesis.

The graphite addition increased percent elongation from 19 to 21%, ultimate tensile strength from 545 to 552 MPa, and yield strength from 348 to 357 MPa.
The maximum extension in the length of the test specimen was taken as the measure of the flexibility of the membrane reported in terms of percent elongation.
Laboratory investigations indicated that the steel used was ASTM A5]6 Grade 70 carbon steel with 540-MPa tensile strength, 304-MPa yield strength, and 29 percent elongation.
These elastomers possess high values of percent elongation at break, while the mechanical properties of elastomers remain consistent over a wide range of service temperatures.
Measurements included the ultimate tensile strength, the tensile strength at yield and break, percent elongation at yield and break, and the modulus of elasticity.
