Strength of materials terminology: name the energy stored under elastic loading When a body is loaded within the elastic limit, it stores recoverable energy. Identify the correct term for this stored energy (overall, not per unit volume).

Mechanical Engineering Strength of Materials Difficulty: Easy
Choose an option
  • A
    Resilience
  • B
    Proof resilience
  • C
    Strain energy
  • D
    Impact energy

Answer

Correct Answer: Strain energy

Explanation

DefinitionsStrain energy: total elastic energy stored by a body under load, recoverable upon unloading (within elastic limit).Resilience: ability to absorb energy elastically; commonly expressed as strain energy per unit volume.Proof resilience: maximum strain energy stored up to the elastic limit.Impact energy: energy absorbed during impact testing (fracture toughness context).

Final AnswerStrain energy.
