Which term describes the material's ability to be pulled to the point of fracture?

Explanation:
When a material is pulled in tension until it fractures, the property being described is its tensile strength. This is the maximum stress the material can withstand under tensile loading, usually measured as force per unit area (like MPa or psi) at the point of failure. A tensile test records the stress at which the sample breaks, giving the material’s ultimate tensile strength. This makes it the best description for the ability to be pulled to the point of fracture. The general term “strength” is too vague, “durability” relates to long-term wear and environmental resistance, and “ripple effect” isn’t related to material properties.
