Choose an option
-
AOnly: The energy stored within elastic limit is called strain energy
-
BOnly: The maximum strain energy stored is proof resilience
-
COnly: Proof resilience per unit volume is modulus of resilience
-
DAll of the above statements are correct
Answer
Correct Answer: All of the above statements are correct
Explanation
DefinitionsStrain energy: total elastic energy stored in a body under load (recoverable).Proof resilience: maximum strain energy up to elastic limit.Modulus of resilience: proof resilience per unit volume.
Final AnswerAll of the above statements are correct.
