FredGarvin - Question For You Please

[vdash103]

FredGarvin - I didn't know how else to reach you and wasn't sure if you would receive a message if I responded to a thread that was started by someone else in which you responded. Anyhow, my question is on compressive stresses for ball and socket type bearings.

You responded to a post in 2007 on this topic and the link is: https://www.physicsforums.com/showthread.php?t=206257

I'm trying to find more information specifically what book your equation came from. I would like to read up on background information for this equation.

Any help you can give is appreciated.

Thank You

Fred hasn't posted since February, unfortunately. You might try PM'ing him, in case he is checking those messages.

I respond as the official agent for Fred Garvin. He is currently occupied with Lady Gaga, but will be glad to answer your questions after his shower.

berkeman,

Can you tell me how to PM him? I was looking for that option and couldn't find it.

Thanks

When you are looking at a post of Fred's you left-click on their underlined user name. That exposes several options, including sending them a PM.

Danger,

Haha - thanks!

My pleasure. Now, please do me a favour and make sure that he never sees that post.

FredGarvin must have his PM settings disabled...it won't let me.

Is there any possibility that

https://www.amazon.com/dp/0070725411/?tag=pfamazon01-20

is the book that FredGarvin used?

 

[john.phillip]

The book is "Roark's Formulas for Stress and Strain" and the equation comes from Table 14-1, chapter 14, p.702 (7th edition, 2002).

For background information, look for hertzian stress or contact stress.

Thanks!

Notice that Fred refers to "the bible, Roark's." That is of course, Roark's Forumlas for Stress and Strain.

That is of course, Roark's Forumlas for Stress and Strain.

Unless Roark took lessons from my ex-wife, he has no idea about stress and strain.
