Correct Answer - Option 4 : toughness
Explanation:
Strength is the ability of a material to resist the externally applied forces without breaking or yielding.
Fatigue: Materials subjected to repetitive or fluctuating stress will fail at a stress much lower than that required to cause failure under steady loads. This behavior is called >fatigue.
Toughness is the property of a material to resist fracture due to high impact loads like hammer blows
Creep the slow and continuous elongation of a material with time at constant stress and high temperature below the elastic limit is called creep.
Malleability is the property by virtue of which a material may be hammered or rolled into thin sheets without rupture. This property generally increases with the increase of temperature.
Malleability is the ability of a metal to exhibit large deformation or plastic response when being subjected to a compressive force.
Ductility is the capacity of a material to undergo deformation under tension without fracture in the material that property of a body is known as Ductility. E.g. Wire Drawing, etc.
Endurance or fatigue limit is defined as a maximum value of the completely reversed bending stress which a polished standard specimen can withstand without failure, for an infinite number of cycles.
Elasticity is the property of a material to regain its original shape after deformation when the external forces are removed.
