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 primary measurement?Flexural Modulus, Yield Strength, and Ultimate Flexural Strength
2. What is the key test configurations?Three-point bending and four-point bending tests
3. How does a soken tester measure bending?It puts a controlled weight on the material and watches how it bends. The machine records the force and the amount of bending so scientists can calculate stiffness and strength.
4. Why do scientists use a soken tester?Scientists use it to make sure things like bridges, airplanes, and gadgets stay safe and don’t break. The data helps choose the right materials and design strong parts.

Flexural Modulus: A measure of a material's stiffness or resistance to elastic deformation under bending.
Yield Strength (Flexural): The stress at which a material begins to deform plastically under bending.
Ultimate Flexural Strength: The maximum stress a material can withstand before fracturing when subjected to bending.
