2.
After how many cycles did the rotating component show cracks?
2 million cycles
500,000 cycles
1 million cycles
250,000 cycles
Explanation:
John says the rotating component shows cracks after 500,000 cycles.
3.
What does John say is the main cause of the early fatigue?
Excessive temperature during testing
High stress concentration near the shaft fillet
Low-quality material
Poor surface finish
Explanation:
John states that high stress concentration near the shaft fillet is the main cause.
4.
What can be inferred about the material used in the component?
It caused the cracks after 1 million cycles
It is likely acceptable and not causing the fatigue problem
It has already been redesigned successfully
It failed because it did not meet standards
Explanation:
John says the material meets all standards and is not the issue, so it is reasonable to infer the material is acceptable and not the cause of the problem.
5.
What will John and Emily do next?
Replace the material with a new alloy
Stop testing the component immediately
Increase the design target to 500,000 cycles
Propose design changes and run new simulations
Explanation:
