Which statement describes tensile strength?

• A. The ability to withstand being pulled apart
• B. The ability to withstand pressure on the surface
• C. The ability to resist heat
• D. The ability to resist bending

Answer: (B)

Tensile strength is the maximum stress a material can endure when it is pulled in tension before it fails. It describes how well a material resists being pulled apart along its length, which is exactly what a tensile test measures as the load increases until fracture. The purpose of this test is to quantify how much pulling force the material can withstand before breaking, typically expressed as stress (force per unit area).

The idea described as resisting being pulled apart is the one that matches this concept. Resisting pressure on the surface relates to how a material handles compressive or bearing loads, not pulling forces. Resisting heat concerns thermal properties, not mechanical strength under tension. Resisting bending refers to flexural or bending strength, which involves curved loading rather than pure axial tension.
