Fatigue life is the number of cycles a structure part can take before it breaks. A cycle is when the stress reverses or changes about its mean value as happens during vibration for example. Usually fatigue life is expressed in number of cycles; for example a steel part of a given strength may have its strength reduced in half after 1,000,000 cycles due to fatigue.
Im going to throw in the trick answer: change the shape of the part in question to improve the fatigue and strength properties of the material in question.Answer 2Yes. Fatigue requires repeated cycles of loading. If you design a part with low strength but only has a few load cycles throughout the life of the part, then it will never fatigue.There are several application of Bolts that have low fatigue loading cycles. The screws attaching the interior of your car are low strength and they last forever---because there is very little load cycles applied to it.Another example: Wooden chair legs never break under fatigue. I wouldn't say that they are high strength part.
Surface treatment affects the endurance strength, which is used to calculate the safety factor. Surface fatigue inevitably occurs for all materials in high contact-stress applications, causing part failure after thousands of repeated cycles. Failure is evidenced by pitting and eventually spalling.
Yes it will bring down the fatigue life and the material will not endure at any point. Degrading nature of fatigue loading on the materials is compounded by the corrosion interaction. Synergistic damage - The damage will be more than the addition of damages due to corrosion and fatigue loading. The formation of intrusion and extrusion due to fatigue loading leads to the notches. The corrosion media will enter the notches and forms oxide with the base metal and it will be passive to further corrosion. But the fatigue loading will disturb the passive layer and facilitate the media to corrode the fresh material. Hence it will drastically decrease the fatigue life of the material.
The breaking strength is always greater than the yield strength.
The tensile strength of concrete is 10% of it's compressive strength.
The fatigue strength of mild steel refers to the certain conditions whereby the mild steel suffers fatigue failure.
It means you have strength from being fat
Fatigue means lack of strength , exhaustion etc. For ex: i was fatigue after working endlessly to clean up my house

to drain of strength or energy, wear out, or fatigue greatly, as a person
The quality or state of being weary or tried; lassitude; exhaustion of strength; fatigue.
"Physical or moral strength to resist or withstand illness, fatigue, or hardship; endurance."
There is no one answer for this question since there are different ways to measure strength. There is absolute strength (maximum force), dynamic strength (repeated motions), elastic strength (exert force quickly), and strength endurance (withstand fatigue).

peripheral fatigue originates in the exercising muscles; central fatigue begins in those various areas of the brain working in concert, and which sent efferent signals to the working muscles to ease strength of contraction in order to preserve homeostasis.
