Why is it important for engineers to understand a material's properties?
To make the product heavier
To increase the cost of manufacturing
Because performance is linked to a material's properties
To make the product more complex
Why is density used to identify a material?
Because density alone is sufficient to conclusively identify a material
Because density is the only property that can be easily measured
Because density is a unique property that remains constant regardless of the amount of material present
Because density is directly related to a material's color and appearance
