A steel rod with a notch has a maximum stress of 250 MPa when subjected to a tensile load. If the nominal stress is measured at 100 MPa, what is the SCF? Discuss its implications if this component operates within a cyclic loading environment.
💡 Hint: Use the SCF formula and think about the effects of cyclic loading.
Explain how varying SCF values could influence the decision of selecting materials for a mechanical part that will undergo dynamic loading and provide an example with detailed reasoning.
💡 Hint: Consider the relationship between material strength and SCF in your response.
