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...
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...
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...

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...
Can someone help me out or point me to a good web resource?
I need to calculate bearing stress and, frankly, I don't think this was covered in school.
Simply, imagine a piece of U-Channel with the open end facing down. Drill a hole through one side and out the other. Put a bolt through it...
I need to insert an SW picture into a power point poster. I'd like to match the backgounds. How do I change the background color on my SW display?

Can the Young's Modulus of a material change?
If I heat up a material, it can become more elastic. If I freeze it, it can become more brittle. Do we say that the Young's Modulus has changed?
I ask this because I had a recent conversation with a biochemist who was telling me that the Young's...
What are these latches called. You find them on heavy duty steel shipping cases (bigger than a trunk, smaller than a car). They have triangular shaped handles and some sort of hook...I believe.
Look at page 10 on this link:

In any case...
Hi,
Do all case manufacturers design their own edging to encase their seal with which to close a case (as in a large box to put stuff in). I can find a billion companies that make seals and gaskets and a million companies that make latches. What about the aluminum frame that protects...
I'm looking into rotational molding as a design option for a composite container. I don't have any experience with this and was wondering if someone could point me to a good link or offer some pros & cons about the process.
Thanx -Barry
I've been moved to a new group where I work and don't have a computer. My boss said to find one less than $5,000 and he'll buy it.......and pretty much left it at that. I've never spent more than $600 on a machine, so I'm kinda in the dark and he's not one to be bombarded with questions.
So...
I'm a competetive triathlete (and an engineer) and took a swim clinic last week. One of the things I was taught was that by making little "S" patterns with my hand as I pull myself through the water, I can create more resistance with which to pull me through. I tried this and noticed that the...
I just read the electrical thread and got some real good insight. However, I have some questions myself.
I am graduating with a BS in ME in a couple of months and am currently looking for jobs. I'm a little older than most students (early 30's) and have a previous career from a previous...
I have a machine that counts pails on a conveyor belt as part of its process. If the machine is maualy operated, it resets the count to zero.
I want to interface something into the PLC that will allow an operator to input what the count should be after resetting. I'm assuming there should be...
Anyone know where I can find a business that will curve plywood for me? I'm looking to laminate three thin sheets together about 8ftx2ft. I need to do a bunch.
Thanks - Barry
