Associate Safety Professional Practice Exam

Which of the following statements about tensile strength is true?

1. It refers to a material's resistance to bending

2. It is only relevant at high temperatures

3. It describes how much stress a material can withstand before breaking

4. It indicates a material's flexibility when under tension

The correct answer is: It describes how much stress a material can withstand before breaking

Tensile strength is defined as the maximum amount of tensile (pulling) stress that a material can withstand before failure occurs, typically measured in units of force per unit area, such as pounds per square inch (psi) or megapascals (MPa). This property is crucial in material selection for engineering and construction, as it helps predict how materials will behave under stretching or pulling forces. Understanding tensile strength is essential in applications where materials are subjected to tensile loads, such as in cables, beams, and structural components. The ability of a material to resist breaking when tension is applied is a fundamental aspect of its mechanical properties, making this statement accurately reflect the true nature of tensile strength.
