Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the historical development?Originated from processing natural fibers (plant, animal) through twisting techniques
2. What is the key engineering parameters?Material composition, twist rate (S-twist/Z-twist), and thread count influence performance
3. What is string and why is it important?String is a strong thread made by twisting many fibers together. It can tie, bind, and hang almost anything, from nets to clothes.
4. How do we make string stronger?Twisting fibers together creates friction that keeps them from pulling apart. This makes the string stronger and more resistant to wear.

Tensile Strength: The maximum stress a material can withstand before fracturing when subjected to a pulling force.
Abrasion Resistance: The ability of a material to withstand surface damage caused by rubbing or scraping.
Material Science: The study of the properties of materials and how they are used in engineering and design.
