It's been a long time since I had to do anything like this and my old ME training is rusty. I need to determine the tensile strength for a threaded hole. As the hole is under the normal rule-of-thumb depths for full bolt strength, AND the material is weaker than the bolt, I figure the weak link...

Guys:
Long time since I've had to do these simple calcs. Gettign old, I barely rememebr the details on accelleration due to gravity :). Can one of you confirm I'm not doing something dumb with my mass and weight conversions?
Problem: I have a weight that is 20lbs (bathroom scale). I am...
Hi guys:
I'm a ME but don't normally do much structural stuff. I built my basement home with MPC floor trusses above the basement. I have discovered one of them has a break.
Trusses are top chord bearing on one end, 18' span, 20" deep, 16OC. Design was supposed to be for l/480, I dont'...
I'm new to 3D but muddling my way through it failry well. But I've run into an issue I can't figure out.
To explain I'll use the example of a rectangular block. I want to resize its height by selecting it, then dragging it's corner handles. I can get it to go left-right, but not up-down. I...
I have a small manual mill that I use with a tapmatic head to make some steel parts. My parts are initially cut for me, from 1/4" thick cold rolled material with a waterjet. I finish drill the holes to be tapped on the mill, then tap.
I use a non-sulpher cutting fluid manually applied to tap...
I am working on an optimized residential duct design usign Manual D equivilant friction method.
All ducts are located in the same space that is being conditioned (basement). I will have some rigid, and some flex ducts.
I would like to keep the friction losses down as much as possible for both...
