1889Engl. Mechanic 27 Dec. 355/2 There is..a kind of elongation by striction, which in the case of a direct pull, is produced with a constant load applied at a rate accelerated up to the point of rupture.
2. Geom. In a skew surface, curve or line of striction: see quots.
1875P. Frost Solid Geom. (ed. 2) I. 297 The curve which is the limit of the polygon formed by joining a, b, c, d,..at which the imagined membranes would have the greatest density, is called the curve of greatest density; it is also called the line of striction. 1889Cayley Math. Papers I. 234 The curve pqr..is said to be the minimum distance curve (or curve of striction). 1892Ibid. XIII. 233 Supposing the distances PQ1, P1Q2, P2Q3, &c. to be all of them infinitesimal, we have a skew surface containing upon it a curve P1P2P3, &c., which is the line of striction, viz, this is the locus of the point on a generating line which is the nearest point to the consecutive generating line. |
