Which statement does not describe a Safe-Life Design?
Understand the Problem
The question is asking to identify which of the provided statements does not accurately reflect the principles of a Safe-Life Design in engineering. This involves understanding the definitions and implications of Safe-Life Design metrics.
Answer
Statement (a) does not describe a Safe-Life Design.
The statement that does not describe a Safe-Life Design is (a) A part fails at 5,000 cycles and the OEM uses a 'life factor' of 6 to determine a Safe-Life of 30,000 cycles.

The statement that does not describe a Safe-Life Design is (a) A part fails at 5,000 cycles and the OEM uses a 'life factor' of 6 to determine a Safe-Life of 30,000 cycles.
More Information
Safe-Life Design ensures that components are removed before any damage occurs. Using a 'life factor' to extend a product's expected life despite failure does not fit the Safe-Life Design model.
Tips
Common mistakes include misunderstanding the Safe-Life concept as merely predicting failure rather than preventing any damage before removal.
