Thanx guys. To be clear, a manager asked me if I could hunt down this formula. He used it back when he was in the military. It's supposed to be very simple. The idea is that you plug the numbers in and if gives you a rough idea if it is even worth considering. ie If that subcomponent only...
Quick question. There is supposedly a forumla out there that helps you determine if you should stock a subcomponent or not. ie Do I want to stock break shoes or should we just stock the whole break assembly, as an example.
The forumla, to the best of my knowledge, contains the following...
Hmmm....I seem to be having a hard time explaining myself (ran into this problem on another forum).
I'm an engineer working in diagnostics. We have flags that come up on our machines as "errors." I checked the data base that maintains the logs of all 169 machines in Europe for the last month...
I'll try to simplify the terms.
I have a total population of 167 widget machines that run 24/7. Each keep a running error log. I've sampled 25 widget machines for 14 days worth or information and these are the results:
3 machines produced errors during the 14 day period.
There were a total...
Wow....you guys are still responding. Thanks. No, we needed holes to get access to the tool side of th epart since we were infusing from the middle and not the ends.
I found a company in NJ called mahogany that sold some decent stuff. The funny thing is the project is now dead (which I knew...
I don't really know a lot of these answers. I'm kind of in between a technician who doesn't really know math and my boss who doesn't remember the formula and is very busy.
I know that it is a composite sandwich structure that is udergoing 3 point bending. The static fatigue tests showed a...
I have a set of samples with a large standard deviation for ultimate strength. We are going into fatigue testing and I need to calculate what load to use.
I have Norton's Machine Design as a reference but it only gives a table for steel (Sd=0.08 of mean) and shows:
90% at .897 of ult. str...
I think I have a pretty good idea, and I know once I get to the interview more questions will be answered. However, I'd like to know a little more about this field before the interview. Can anyone give me a good idea what kinds of tasks one would likely do? Is it just managing a shift or does...

Thanks. My first prototype was done with a ruler, a sharpie, a hand held drill, and a very sore arm ; )
One of the suppliers had reccomended the studed board. That may have to be the next step.
Thanks.
Thanks for the tip, but honeycomb is no good. I'm infusing a sandwich structure via VARTM. I've never done this with honeycomb, but the weight and cost of all the resin that would fill the honeycomb cells would be terrible for this application.
We're using an impermeable foam core and putting...
Does anyone know of a company that sells foam core that already has holes? I talked to General Plastics, but they don't do it anymore.
I'm looking for PVC or Polyurethane in ~4lb density.
Also, do you know who has affordable scored foam?
I'm looking for something a little sturdier than strut channel yet still pretty cheap.
Basicaly, I need an easy and convenient adjustable rail system to attach different large pieces of equipment to (180 lb peices). Strut channel would be perfect except its kind of weak.
8084 might be good...
