Question

For a 1040 steel solid square bar, determine the endurance limit or Se based on the following information describing the loading condition, reliability factor, etc.

•The Sut has been tested at 620 MPa (1040 steel)
•The bar is 125 mm, solid square, hot rolled finish
•The operating temperature is 525 °C maximum
•The loading is fully reversed torsion
•The clients would like a 99.99% reliability factor
Objective: Determine Se
