My requirement was 25 ft*lb/in. But 23 has been accepted! Thanks, JP

Well, 4 dowell pin hehehe..

Oh yeah really? Higher number on charpy test with a Q&T ? that's weird!

Just so you know, after a normalization, my charpy was way better! FROM: 12 ft·lb/in longitudinal and 14 ft·lb/in transversal TO: 60 ft·lb/in longitudinal and 23 ft·lb/in transversal

Hi! I would like to know if someone could help me find a North America equivalent for 16MnCr5. This is a material from germany. Thank you very much. JP

That is what I think, but I would like to know, how much. 5%, 20%, 35% ? That's a huge difference. Thanks, JP

Hi! I would like to know if a stress relieve should affect the result of a charpy test on tubing. (my tube is 1026 11" OD x 2" wall). I've sent my tube to a firm for a charpy test on hot rolled 1026 tube. My results were 12 ft·lb/in longitudinal and 14 ft·lb/in transversal. I need to get a...

This is exactly my problem, I don't know how to model my situation.

Hi, I would like to calculate the function of a rotating disc that has 2 spring slowing it down. (look at my pictures to understand) Let say I turn my disc 90 degrees clockwise and release it, it is going to oscillate a certain moment than stop. I want to plot that function and to have a...

Hi, First, I want to thanks all of you for helping (especially Fex32). I'm doing another post because my english is bad and I want to "try" to be a bit more precise. So here's what I want to do; I want to model on Matlab Simulink the rotation of a disc around a shaft. That disc when at initial...

This is the application: http://www.youtube.com/watch?v=jgIRu39fH18 I need to simulate that disc movement on simulink.
