We make an assembly where we press two parts together, that are 1/2 inch in diameter. One diameter is smooth, the other is knurled. I'm testing parts to failure to capture peak torque values, based on amounts of interference. 2 Link to comment Share on other sites More sharing options...

Where does @denniS apply? 1 2 Link to comment Share on other sites More sharing options...

He also said that it's fun until you are scheduled for 4 hours on the test track and it's 38 degrees and raining. 1 Link to comment Share on other sites More sharing options...

In the early 2000s I worked closely w/ the OEM we sell this assembly to, on a redesign. It was like a 2 year long science experiment/physics lab I love this type of stuff. The engineer I was working with felt the same as me. Link to comment Share on other sites More sharing options...

Their first job was to make radio towers come down and then figure out why. They could not believe they were getting paid to have fun. 2 Link to comment Share on other sites More sharing options...

We had to have some valve bodies hydrostatically tested til failure. We don't have this capability so we went to a local lab. The maximum pressure reached was 27,300 psi Nothing exploded the failure was internal. With a safety factor between 10-19, I think we're good.
