We are looking at requirements to calculate how high the logistics folks can stack a variety of boxes/pallets in the warehouse. Any Packaging engineers here or folks who could recommend an appropriate MIL-Spec or other documentation in the public domain? thanks in advance.

I'm interested in getting feedback or pointed to resources pertinent to creating a "FEA Plan". What I mean by the term plan, would include a document used by an engineering department describing how FEA fits into an overall companywide Engineering Plan. For example, I expect there will be some...

I know the question has been asked regarding helical lock washers, "Is a lock washer beneficial?" and I have seen the NASA reports and threads on this website with the consensus that NO helical lock washers are in essence useless. Now, I didn't see anything regarding what I call a star washer...

If anyone could recommend material(s) to meet the following requirements, it would be appreciated: 1. Steel 2. Must be formable (90 degree bend max) 3. 50Ksi yield minimum 4. Corrosion resistance is a non-factor 5. Cost not a hard requirement but cheaper is better 7. Thickness range...

Does anyone have a reference for a vibration/shock specification used for soldier/personnel carried electronic gear such as a backpack mounted radio? MIL-STD-810 doesn't seem to address the topic. Thanks in advance.

Forgive me if this has already been answered but I couldn't find it. Does anyone have a published fatigue curve for A36 plate? Thanks in advance.

Who will be at SWW 2010 in CA this year?

Does anyone have a fix for the following error message. "openclipboard failed". It occurs when trying to insert a part or assembly into another assembly. I am running Win XP 64 on a Dell T-7400 workstation. SolidWorks 2009 SP 3.0 Thanks in advance

Is anyone running Windows XP(32) and SW 2009 SP1.0 getting multiple processes running of the executeable SldShellExtServer.exe? It appears to happen when a Windows Explorer window is opened to a directory that has SW files in it. As the program generates a thumbnail, these multiple processes...

For those who have experience designing custom electronics devices and enclosures for industrial and military applications please respond. We are designing a custom enclosure that will be air cooled. We don't have a specification for filtration but know it will be in an environment where the...

O.K. Hopefully the title will get some attention and elicit some good advice. The situation is this. I work for a relatively large defense contractor. We are currently in a work up-swing. The company is actively recruiting with one of the positions being a perfect fit for me except I'm over...

Can someone supply a yield strength number for 6061-T651 in the as welded condition and a source? Thanks,

My question relates to the evaluation of an AC system for a vehicle. I reviewed a brief that makes a statement in part, "limit exposure of refrigerant lines (fire hazard)". The context of this statement was in regards to safety. The statement puzzles me because I have a good amount of...

Forgive me if this is a stupid question but my Google skills seem to be failing me. We would like to purchase a 2 ton condenser that uses r-134a. The plan is to use it in a "test bed" for developing various line set configurations, evaporator sizes and the like. We envision the condenser being...

My question is on a topic I don't normally deal with: We are running some compressed air lines in a production area to supply air tools. For those that do this on a regular basis, any advice or known pitfalls would be helpful to know. In my mind sizing the compressor should be fairly simple...

Can someone tell me what the signifigance of the "extra" 1 is when comparing the following two aluminum tempers?aluminum 6061-T651 versus T6511. Thank you

Hope this is the correct forum. The question is specifically in regards to large trucks(class 8) and or large military vehicles. assuming the generic wisdom is "high center of gravity bad" and "low center of gravity good", the following question is asked. Are there any SAE specifications (or...

If you folks were to review a design for a vehicle AC system that included a manifold with NPT connections, what would you say? Seems to me that NPT is a bad choice for moving R-134a, won't it bleed out over time.(even with pipe dope) Correct me if I'm in error. thanks

I had a PM at work say "so and so" has a Master's Degree in Failure Analysis". I almost choked on my coffee laughing as I beleive the individual is mis-informed. So my question. Is here anyone aware of an accredited univerity that offers a MS in "Failure Analysis" Thanks for your input.

A couple of questions here with the aim of evaulting FEA stress results. Problem: A 6063-T52 aluminum tube is subjected to a clamping force that results in localized Von-Mises stress in excess of yield. Questions: 1. Can anyone provide data on the compressive strength of the above mentioned...
