Which one of the following is the result of applying a load to a wire below its modulus of elasticity on a load deflection diagram ?
Correct answer: C. Spring back
- A. Fracture of the wire
- B. permanent deformation
- C. Spring back
- D. Increase in stiffness
Explanation
A load below the elastic limit produces only elastic deformation, so the wire returns toward its original shape when the load is removed, known as spring back. Strictly, the stem should say below the elastic or proportional limit rather than below the modulus of elasticity.
