What's the difference between extensometer and length?
Extensometer
Definition:
(n.) An instrument for measuring the extension of a body, especially for measuring the elongation of bars of iron, steel, or other material, when subjected to a tensile force.

Length
Definition:
(a.) The longest, or longer, dimension of any object, in distinction from breadth or width; extent of anything from end to end; the longest line which can be drawn through a body, parallel to its sides; as, the length of a church, or of a ship; the length of a rope or line.

(a.) The quality or state of being long, in space or time; extent; duration; as, some sea birds are remarkable for the length of their wings; he was tired by the length of the sermon, and the length of his walk.
(a.) A single piece or subdivision of a series, or of a number of long pieces which may be connected together; as, a length of pipe; a length of fence.
(a.) Detail or amplification; unfolding; continuance as, to pursue a subject to a great length.
(a.) Distance.
(v. t.) To lengthen.
