Question

_______ is a material property that pertains to local resistance to plastic deformation, such as scratching or denting. It is often measured by poking a material with a very hard tip (like diamond) and measuring the size and depth of the resulting crater that forms.

Answer 1

Answer: hardness

Explanation:

Hardness is a measure of a material's ability to resist plastic deformation. In other words, it is a measure of how resistant material is to denting or scratching. Diamond, for example, is a very hard material. It is extremely difficult to dent or scratch a diamond. In contrast, it is very easy to scratch or dent most plastics.
