Correct Answer - Option 2 : titanium
Explanation:
Endurance strength:
For cyclic loading conditions, endurance strength is considered. Endurance or fatigue limit can be defined as the magnitude of stress amplitude value at or below which no fatigue failure will occur, no matter how large the number of stress reversals takes place. In other words, leading to an infinite life to the component or part being stressed. For most ferrous materials Endurance limit (Se) is set as the cyclic stress level that the material can sustain for 10 million cycles.
Among the given material Titanium has the highest capacity to absorb the maximum stress for an infinite number of cycles.
- Titanium is a strong and lightweight metal. Alloys containing titanium are known for their high strength, low weight and corrosion resistance. Being strong as steel titanium is about 40% lighter in weight.
- Titanium alloys are used in the aerospace industry, medical industry, chemical and military hardware, and sporting equipment.
