Actually, let me adjsut the question... a quick google brought up a lot of info... what spec seems to be the aero industry standard for this process?

Could you tell us more about "brush cadmium plating"? Do you have material and application specification references by chance? Thanks.

For small areas of cad plating that have worn, or been machined, off of steel and nickel-aluminum-bronze (e.g. bushings), what are folks seeing done to protect the surface without having to re-cad plate?

So how did the interview go and what all did they ask?

Anybody have a copy of the TRA yearbook from the last few years thatyou'll sell to me? For what I'm doing I really don't need a current copy. Thanks.

Can anyone point me to a sample tire drawing? Nothing proprietary, just a place to start.

Ok, to start... if I have a target speed requirement and load capability requirement where do I begin for material allowables, etc for determining how many plies I need. Are there industry standard tables or specs I can point to?

I have a project where I need a custom sized tire similar to an ATV tire or a turf tire. Nothing else is out there that will fit my exact needs and I would like to get a tire built. Can any of you help me answer some basic engineering questions for pneumatic tire design? I've searched for...

Sure, I would be happy to invite you (and others) to the discussion group. Shoot me your email address at removethis_sigmatero@yahoo.com and I'll send the details. Thanks for being open to the idea. BTW, I was just comparing solutions for crippling of stringers and how Peery deals with flange...

40818…there's several reasons for wanting to create the answer key. 1. Based on quite a few posts on this list it seems that folks are hungry for textbooks on fundamental aircraft engineering stress analysis techniques. Aircraft Structures by Peery certainly fits this criteria. 2. Folks...

If it matters then take care of your stackup with dimensioning at the assembly/installation level.

I’ve been trying to find an answer key for Peery’s original edition of Aircraft Structures and haven’t had any luck. I’ve been in contact with numerous DERs, professors, and even Peery’s son and daughter. None of them knew of an answer key and the general consensus was that Dr. Peery didn’t...

The four classics are Bruhn, Niu, Peery, and Flabel. From there you can branch out into the mechanical side with Roark, etc.

Got it, good stuff, thanks.

I sure hope it exceeds "guaranteed minimums", at least 99% of the time with a 95% confidence (for A-basis) :) I really can't use actual as-tested material properties or S-basis since I need to compare to what was tested and then specify material condition accordingly on the print. IOW I don't...
