What are the reasons that the Palmgren-Miner law proves that environmental stress screening (ESS) will precipitate latent defects without taking useful life out of a product? Choose all that apply.
1. Stress is concentrated around defects
2. The ESS is run for a short time, while the product life is a long time.
3. A product can withstand relatively few cycles at a high stress level
4. A product can withstand many cycles at a low stress level
5. The slope of the S-N curve of a material is between 8 and 12 for most materials.
