What Is The Term Fatigue Cracking And State With Reasons Two Factors

1.	What Is The Term Fatigue Cracking And State With Reasons Two Factors Of Crankshaft Operation Which Have The Greatest Influence On The Likelihood Of Fatigue Cracking ?
Answer» FATIGUE cracking occurs when the PRIMARY cause of crack propagation is due to the FLUCTUATING nature of the stress applied to the component. The following factors could produce fatigue cracking: HIGH combustion PRESSURES, increasing the bending stress applied to each crankshaft throw Excessive crankshaft bending due to a main bearing failure, which increases the crankshaft bending stresses. Fatigue cracking occurs when the primary cause of crack propagation is due to the fluctuating nature of the stress applied to the component. The following factors could produce fatigue cracking:

FATIGUE cracking occurs when the PRIMARY cause of crack propagation is due to the FLUCTUATING nature of the stress applied to the component.

The following factors could produce fatigue cracking:

HIGH combustion PRESSURES, increasing the bending stress applied to each crankshaft throw
Excessive crankshaft bending due to a main bearing failure, which increases the crankshaft bending stresses.

Fatigue cracking occurs when the primary cause of crack propagation is due to the fluctuating nature of the stress applied to the component.

The following factors could produce fatigue cracking:
