Correct answer: C. Impact strength
- A. Machinability
- B. Endurance limit
- C. Impact strength
- D. Corrosion resistance
Explanation
A notched bar concentrates stress at the notch, and the impact test measures the energy absorbed during sudden fracture. Thus, it determines impact strength rather than endurance limit or machinability.
