Which term describes attributes such as material and density, i.e., physical properties?

• A. Physical Properties
• B. Model
• C. Scale Model
• D. Solid Modeling

Answer: (A)

Physical properties describe attributes such as material and density. These are inherent characteristics of a material and can be measured without changing the material, helping engineers understand weight, strength, and behavior. Density tells you how much mass is packed into a given volume, which directly affects performance, while knowing the material indicates what properties (like hardness or conductivity) are likely relevant. In contrast, a model or scale model is just a representation of the object’s form or size, and solid modeling focuses on geometry and structure in CAD. They don’t describe the material’s intrinsic characteristics, so the term that fits attributes like material and density is physical properties.
