Question

The resistance to fatigue of a material is measured by?

Answer 1

The resistance to fatigue of a material is measured by a) Elastic limit b) Ultimate tensile strength c) Young's modulus d) Endurance limit.

Answer 2

Answer:

The "resistance to fatigue" of a material is measured by endurance limit.

Explanation:

• The fatigue of a material is the stress or strain it undergoes when subjected to repeated processes or cycles which lead to break down of its structure and ultimately fracture of the material.
• The fatigue strength is the highest or maximal strength that a material can resist or withstand for a certain number of cycles without breaking or fracturing.
• This strength is also known as and measured by endurance limit.
• Endurance limit is denoted as Se, $\sigma N$ where N is the number of cycles.
