What type of line stretches to nearly one and 1/3 its original length before failing?

Explanation:
The property being tested is elongation at break—the amount a line can stretch under load before it fails. Nylon lines are known for high elongation due to their viscoelastic polymer behavior, giving substantial stretch before breaking. They can extend by roughly 20–30% of their original length, which means they can reach about 1.2 to 1.3 times their initial length before failure. That gives nylon a lot of give and makes it good at absorbing shock, though it means more length change under load. Aramid fibers (like Kevlar) stretch very little—only a few percent—so they stay tight under load and fail with little warning. Polyester stretches less than nylon as well, offering moderate elongation but not the same level of stretchiness as nylon.
