The following figure shows what happens: (a) there is a permanent deformation; (b) the slope of the ... the bending tools (which determine how much to bend to get the correct angle) ?
Carbon and Low Alloy Steel Casting Mechanical Properties
www.sfsa.orgthe amount of permanent stretch, plastic deformation, in the tensile bar test. The increase in length is the elongation and the change in area at the point of fracture of the bar is the reduction of area. The ability to stretch without cracking is called ductility. In general, increasing the strength of a steel grade reduces its ductility.

www.tappi.org2.2 Stretch, the maximum tensile strain developed in the test specimen before rupture in a tensile test carried to rupture under prescribed conditions. The stretch (or percentage elongation) is expressed as a percentage, i.e., one hundred times the ratio of the increase in length of the test specimen to the original test span.

Kinetic Isotope Effects in Organic Chemistry
chemlabs.princeton.edu2.There is a new symmetrical stretch in TS structure in which the hydrogen atom has a significant range of motion. This makes the frequency of this stretch highly mass dependent. H C H C v = 2900 cm-1 v = 1350 cm-1 Stretch Bend! Generally primary KIE's for proton transfers occuring by non-linear TS's are on the order of 2.5 - 3.5.
A Second Application of Symmetry
www.chem.uci.eduWe can use character tables to determine the symmetry of all 18 motions and then assign them to translation, rotation, or vibration. We can also tell which vibrations are IR or Raman active. Procedure: 1. Assign x,y,z coordinates to each atom. 2. Determine how each axis transforms for every class of symmetry operation in the group.
