Undergoing, or exerting tension; capable of being stretched or drawn out.

The maximum tensile stress (stretching) that a material can withstand without failure or breaking.

An external force that acts on a body at both ends, parallel to the length, and that if unopposed will tend to elongate it; that is, the material will stretch.

It is a measure of the intensity of the total internal forces acting within a body across imaginary internal surfaces, as a reaction to external applied forces and body forces.
