Thanks for the responses. As far as I can tell, the UNJC stud should fit into the UNC Hole. If it doesn't I will defiantly post results on here.

I have a drawing call out from the 1960s from a certain government agency which calls out a UNJC Stud and Self Locking Bolt, however the hole call out is for a UNC-3B Tapping.
I am trying to assemble a list of Engineering Change Orders and I was wondering if anyone here had experience with...

Change your density to 0.0968 lbm/in**3. (www.matweb.com)
Thats pretty close to what you have.

If you dig around on the net, you can calculate the thread engagement area which you need for an aluminum body and a steel bolt. This will show you that for a softer female body, you will need less depth with a course thread.
So if you are going to use a UN thread, I would suggest a 3/8"-16...
I agree with rb1957.
Glass is technically a liquid in the molecular level; meaning that it does not have an ordered molecular structure. So including in a FEA model can work out to be a nightmare.

In a word. No.
Tolerances should not be held to significant figures, they should be held within the accuracy bounds which are needed. If you need three digit accuracy, and put only two digits, then the machinist will give you a part with two digit accuracy. Conversely, if you give him (or...
I have recently joined the dark side and purchased an Apple. I still have my CAD Machine, but I was wondering if it was possible to install ProE on an Apple. Has anyone tried this and had some luck with it?

It depends on who you want to have turn the handle. If designing something for a child, I would go closer to the 5 lbf, but for an adult 10 lbf should suffice.
Keep in mind which axis you are rotating the handle. 10 lbf rotation is not too bad if you are rotating the handle about the...
I've seen them and played around with them a little bit, but I could not find anything to actually put them to use. The bolts I had used UNC RH Threads and UNF LH Threads.
I guess I should state, that they made an interesting conversation piece when they were on my desk. That was about it...
Granted I have little experience with composites, as well as the material being discussed is currently proprietary. I can say that it is no a glass based composite and the reason which a sealed plug in not being used is because the material has a limited lifespan and we are trying to minimize...
I am working with a weak composite where I have to drill a hole and tap it. From there I have to make a plug from the same material to fill the hole. Due to how brittle the material is I cannot use a standard UNC thread. I have looked into using ACME threads but my manager suggests a round...
Unfortunately, automobiles are complex. The flow field for a car is in incompressible flow unlike an airplane. Since you are so close to the ground, you also have to deal with ground effects. Defiantly a CFD problem that would not be too much fun.
I have been using as HAAS shop to do all of my project work and when I was in school we used HAAS machines. I have not had any problems with either set up. Really either machine brand will function, it is just a decision based upon economics. See if you can get the MTBF of the different parts...
I have a combustion chamber where 26 thermocouples have been attached to measure the temperature of the inside wall of the chamber. I know the material properties and I was wondering if there was a way to determine the heat flux through the combustion chamber wall as a function of time since...
