Elastic PEEasyQuestion 6356

Question

Elastic potential energy per unit volume = ½ × Stress × Strain = ½ × Stress²/Y. This equals:
  1. A
    ½ × Y × strain²
    Correct
  2. B
    Y × strain
  3. C
    Y × stress
  4. D
    ½ × Y/strain²

Correct answer

½ × Y × strain²

Explanation

u = ½ × stress × strain = ½ × Y × strain². Both forms are equivalent. = ½ × Y × strain².
