The ability of a material to withstand an applied force without failing.

Paper 1
The ability to withstand an applied force without failing.
Revise: Metals and alloysStrength concerns resisting forces without failing. Hardness concerns resisting indentation, scratching and wear. Toughness concerns resisting impact without breaking.
Keep strength, hardness and toughness distinct: resisting a load, resisting surface damage and resisting fracture from impact are different abilities.
Low density does not automatically mean low strength. Density describes mass per unit volume, not resistance to force.
Distinguish strength from stiffness: resisting breaking is not the same as resisting bending.
