Cast iron is having very high ___________________?
Correct answer: C. Proximity between its elastic limit and ultimate breaking strength
- A. Tensile strength
- B. Ductility
- C. Proximity between its elastic limit and ultimate breaking strength
- D. All A., B. and C.
Explanation
Cast iron is brittle, so its elastic limit lies relatively close to its ultimate breaking strength and it has little plastic deformation before fracture. It is not highly ductile, and its tensile strength is generally lower than its compressive strength.
