Question
What is a mechanical property?
Answer
An aspect of a material affected by the application of a force.
Question
Strength vs stiffness?
Answer
Strength is the force needed to break it; stiffness is how much it bends before then. A diving board is strong and deliberately not stiff.
Question
Hardness vs toughness?
Answer
Hardness resists scratching and wear at the surface; toughness is the energy absorbed before fracture. Glass is very hard and not at all tough.
Question
Malleability vs ductility?
Answer
Malleability is being hammered or rolled into SHEET; ductility is being drawn out into WIRE.
Question
Elasticity vs plasticity?
Answer
Elastic deformation returns to the original shape when the load is removed; plastic deformation stays. A bent paperclip has deformed plastically.
