Add a one-line explanation of what this file represents

This diagram image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.

It is recommended to name the SVG file “Uniaxial.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

Instructions: on a system with a modern TeTeX or similar installed save the following two files, then run

mpost uniaxial && pdftex uniaxial

You will then need to use ghostscript or similar to make a raster image out of the pdf.
