I found this article and apparently hardening changed the Young's modulus. This is directly in contradiction from what I've found elsewhere...

I was in a discussion with a colleague about grain structure and I think I've misinterpreted what my instructor at university taught.
We covered grain structure in martensitic vs spheroidite of the nucleation vs grain growth of the materials. From my understanding, the martensitic material...
I have multiple objects that are stacking together. I realized parallelism doesn't specify the positive or negative angle of parallelism so objects may be acting in the same parallel stack or against each other.
1.)Is there a way to specify the positive or negative angle of parallelism?
The...
Quick Summary
Screws on parts are going into tapped holes with optimal cycle time
Specified full thread depth of X1 from top of counterbore
Partial tapered thread depth after X1 as X2
I have a screw that is slightly longer than X1 and I need to understand if a human operator could "thread/tap"...
The problem is I want to have a completely flat surface for bonding the surface to another surface. If there's a gap it may cause other problems. Also, thanks for the undercut radius concept. I had no idea people did this on cutting tools to reduce the stress concentration factor and was limited...
I wanted to know if anyone had a background in tool design. Ignoring the stress concentration factor calculations, what is the smallest manufacturable radius for a stepped shaft(milling bit)? Is it impossible to bring a stepped radius down to less than .001" on a milling tool?
I'm working on multiple projects and it seems many mechanical engineers in my group understand frequencies and modal analysis. I have a bachelors degree in mechanical engineering but didn't have any courses in vibrations and response and I feel under taught in this part of mechanical...
I'm designing my first plastic press fit component with metal shaft. I've gone through the calculations however a senior engineer has been telling me the part won't fail in the way I think it is.
The press fit purpose is: Hold the press fit plastic part in XYZ with an additional tool that locks...
It seems trivial but I've honestly never run across this definition in my career. I'm working with a gasket like material with a moveable component underneath it. Do materials have a calculated adhesive force to common materials? I've seen tabulation for the common variables, youngs modulus...
Thanks Chez311, that's very clear and to the point and exactly what I was looking for. My company doesn't have the ASME Y14.5 notes so I have no reference for these items though its called to that spec on the print.
I'm designing a part and I had a question about additional cost but I'm not sure if this really affects my part.
One tolerance on the part is originally called out as .095+- .002
I asked my suppliers if the true nominal value could be called out without additional cost, .0948+-.002.
They...
