What is strength? - Correct Answer - Strength is the ability of a material to withstand a force applied to it
What is ductility? - Correct Answer - Ductility is the amount that a material can be deformed.
What is malleability? - Correct Answer - Malleability is the ability of a material to deform without rupturing. This means that the material can be changed without it breaking
What is hardness? - Correct Answer - Hardness is the ability of a material to resist wear and abrasion. The harder the material the harder it is to make a mark on the surface
What is toughness? - Correct Answer - Toughness is the ability of a material to withstand an impact without breaking. It is the opposite of brittleness
What is brittleness? - Correct Answer - Brittle materials will shatter in response to an impact. It is the opposite of toughness
What is stiffness? - Correct Answer - Stiffness is the ability of a material to resist bending. 1 / 3
