An electric car manufacturer is looking to utilize some stock AISI 8740, hot rolled steel bars that are around 2 inches in diameter for their conveyor system that is being set up to start producing their own batteries. The data sheet shows the the bars to have 132,000 psi tensile strength, 87,500 psi yield strength, and 16.7% elongation. A hardness of 262 Bhn allows it to be finish machined after heat treatment. They keep their workspace at 70°F. What is the working endurance strength, Se? 39,750 psi 28,562 psi 42,500 psi 33,400 psi

Question
An electric car manufacturer is looking to utilize some stock AISI 8740, hot rolled
steel bars that are around 2 inches in diameter for their conveyor system that is
being set up to start producing their own batteries. The data sheet shows the the
bars to have 132,000 psi tensile strength, 87,500 psi yield strength, and 16.7%
elongation. A hardness of 262 Bhn allows it to be finish machined after heat
treatment. They keep their workspace at 70°F.
What is the working endurance strength, Se?
