Introduction: The ability of a material to resist breaking under tensile stress is one of the most important and widely measured properties of plastics including nylon filaments used as fishing line. Most plastics stretch under tensile force and become longer. The percentage of increase in length that occurs before it breaks under tension is called the ultimate elongation of a plastic.
