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.
