In relation to strength, what does specific weight measure?

• A. The weight per unit volume
• B. The tensile strength of a material
• C. The volumetric capacity of a body
• D. The yield point of a material

Answer: (A)

Specific weight measures the weight per unit volume of a material. This concept is crucial in fields like engineering and materials science because it helps to determine how heavy a material is for a given volume, which can influence design, structural integrity, and performance. Specific weight is defined as the weight of a substance divided by its volume and is often expressed in units such as newtons per cubic meter (N/m³). This property is particularly important when considering the overall weight of materials in structures, as it can affect the design loads and stability. The other choices pertain to different material properties. Tensile strength refers to the resistance of a material to breaking under tension, while volumetric capacity relates to the volume a body can hold or displace. The yield point denotes the point at which a material begins to deform plastically. Each of these properties has its significance, but they do not define the concept of specific weight.
