The ability to resist breaking while being pulled or stretched is known as what?

• A. Adhesion
• B. Tensile strength
• C. Flexibility
• D. Elasticity

Answer: (B)

Tensile strength is defined as the maximum amount of tensile (pulling or stretching) stress that a material can withstand before breaking. It is a crucial property of materials used in construction and pipefitting because it indicates how well the material can tolerate forces that attempt to pull it apart. This characteristic is essential for ensuring that pipes and other fittings maintain their integrity under various loads and operational conditions.

In contrast, adhesion relates to the ability of different materials to stick together; flexibility describes a material's ability to bend without breaking; and elasticity refers to the capacity of a material to return to its original shape after deformation. While these properties are also important in material selection and application, they do not specifically measure the material's resistance to breaking when subjected to tensile forces, which is why tensile strength is the correct answer.
