Centrobaric \Cen`tro*bar"ic\, a. [Gr. (?) ? a treatise of
   Archimedes on finding the center of gravity, fr. ?
   gravitating toward the center; ? center + ? weight.]
   Relating to the center of gravity, or to the process of
   finding it.

   {Centrobaric method} (Math.), a process invented for the
      purpose of measuring the area or the volume generated by
      the rotation of a line or surface about a fixed axis,
      depending upon the principle that every figure formed by
      the revolution of a line or surface about such an axis has
      for measure the product of the line or surface by the
      length of the path of its center of gravity; -- sometimes
      called {theorem of Pappus}, also, incorrectly, {Guldinus's
      properties}. See {Barycentric calculus}, under {Calculus}.
