Explain how fatigue and breakage occur.
b) In general, describe the two measures to be taken to prolong fatigue life.
c) A cylindrical ductile cast iron rod, repeated push-pull stress along its axis
It is subjected to the cycle. 107 cycles of fatigue breakage under F = 10,000N load amplitude
Calculate the minimum allowable rod diameter to ensure that it does not occur even at the end. 107
The fatigue limit for this cast iron in the number of cycles is 220MPa. The safety factor in this question is N =
Assume it is 2.
d) How to increase the fatigue performance of carbon steel?
