(a) Breaking Strength
(b) Toughness
(c) Hardness
(d) Stiffness
Ans: (b)
Explanation: Breaking strength is the maximum stress that a material can withstand while being stretched or pulled before failing or breaking so its not related with strain only stress are considered,
Hardness is the resistance of a material to localized deformation so hardness is propositional to accepted load before any deformation at here strain = change in length / original length are not consider.
Toughness is the ability of a material to absorb energy and plastically deform before fracturing and absorb energy per unit volume calculated by area under the stress-strain curve.
