Which material is known for having low tensile strength?

• A. Wood
• B. Concrete
• C. Steel
• D. Plastic

Answer: (B)

Concrete is known for its low tensile strength, primarily because it is a brittle material. While concrete is very strong in compression—meaning it can withstand heavy loads when being pushed together—it does not perform well in tension, which refers to being pulled apart. This limitation arises because concrete's composition and structure do not allow it to effectively resist stretching forces, leading to potential cracking or failure when under tensile stress. In construction and engineering applications, this characteristic means that concrete is typically reinforced with materials like steel (rebar) to improve its tensile strength and overall durability. This combination helps to create structures that can bear both compressive and tensile loads more effectively. Understanding the material properties of concrete, especially its low tensile strength, is crucial for designing safe and durable structures.
