a. [ Gr. (&unr_;) &unr_; a treatise of Archimedes on finding the center of gravity, fr. &unr_; gravitating toward the center; &unr_; center + &unr_; weight. ] Relating to the center of gravity, or to the process of finding it. [ 1913 Webster ]

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. [ 1913 Webster ]
