Show answer and explanation
Correct answer: (C) P–Steel,Q–Glass,R–Bone
Explanation
P shows yielding, a large plastic strain and eventual fracture, characteristic of ductile steel. Q is approximately linear followed by abrupt brittle fracture, characteristic of glass. R represents the lower-stiffness, less ductile bone response in this schematic. Hence P–steel,Q–glass,R–bone, C.
