Can someone reconcile 'e' for me here? What is the intention of 'e'? Moment arm? That's what A-73 suggests. If so, PW-43.1 is a terrible visual.

This is a minor problem, but one that is mildly bothering me, nonetheless. So I thought I'd pose the question here since it's not a matter of functionality but one of aesthetics.
Since Build 7400, the model visuals have been 'squished' like when viewing television broadcasts at 4:3 aspect...
Section VIII, Div 1, UHX 13.3 Nomenclature states for yield stresses:
"NOTE: The yield strength shall be taken from Table Y-1 in Section II, Part D. When a yield strength value is not listed in Table Y-1, one may be obtained by using the procedure in Step UG-28(c)(2)3."
Could someone please...
Is there a provision in B31.1 that calls on PG-52 or any other section of any other ASME Code in regards to ligaments between multiple branch connections?

I'm chasing gremlins and need someone with intimate knowledge of the VW 1.8t boost, ignition, valve (cam) timing control, and fuel management. I can't use VAG-COM until I know where to look (and find someone w/ VAG-COM that I can borrow).
It's a long shot, but I thought this might be a good...
I see a change indicated for the 2011a to Appendix 2, 2-5, but I cannot find the change. I look at our insurance company's tabulation, search the interwebs and look at other insurance companies tabulations, and I see no reference to a change in 2-5. Does anyone know what was updated there? Is...
I'm not sure if this is the correct forum, or if anyone can help with this without seeing a picture (working on it), but there is something strange happening in my mothers lawn.
In a roughly 15-foot square area there are small mounds of clay and other fine soil that seem to be produced by a...

Question: The 'Other Elements' column has a formula:
Ti 6 x (C+N) min, 0.50 max; Cb 0.17
(I want to be sure I understand this formula completely.)
This formula means, with C = 0.030, N = 0.030,
Ti, min = 6 x (0.030+0.030) = 0.36%
Therefore, Ti content is...

Is there an 'industry-standard' accepted tolerance for concentricity between the bolt circle and a slip-on flange I.D.? I cannot find this in B16.5, implied or otherwise. This would be a very useful tolerance for those concerned with fit, and those tolerancing an assembly that uses B16.5...
I have a copy of the Pressure Vessel Handbook, but I'm always looking for more detail. What I could really use would be a combination design guide/interpretation (not official ASME versions)/explanation of motivation for Section VIII. I could also use one for Sections I and IV, but not nearly...
Is a size-on-size corner joint allowed in a vessel of non-circular cross-section? It appears that with the full-penetration joint option in UG-34, size-on-size is precluded by the 1.2*ts requirement. Can anyone find an exception to this in either UG-34 or UW-13...
The subject section states 'Rectangular cross-section vessels per Fig. 12-2(a) sketches (1) and (2) subject to external pressure shall meet the following requirements:'...
Could one interpret this to cover stayed vessels of rectangular cross section (sketches (7)-(10))as well, perhaps...
I have a question about terminology/naming of some branch connections I'm sure are very familiar to all of us. I'm also guessing that my company is not the only having experienced this problem.
The problem: receiving what Penn Machine (www.pennusa.com) calls a 'weld boss' in place of a...
Consider a flange, SA-182 F304 150# class, having a rating at 1000°F of 20PSI. Now what arrives at your shop is certified as SA-182 F304/304L.

This question is general in a sense. I mean to ask it for wherever a required thickness is needed for opening reinforcement, UG-45 nozzle neck thickness, the calculation of an unstayed flat head coefficient 'C', or for coincident ratio, et al.
What equation (UG-27 or Appendix 1), what...
How does Compress determine whether to use UG-27 or Appendix 1 equations for calculating required thicknesses for, say, nozzle reinforcement calculations and unstayed flat head coefficients? I've seen both used in the nozzle reinforcement area calculations in 2 different models of the same...
Rf=mean radius after forming
This question might sound like it has the most obvious answer, but does anyone know this value is calculated?
According to Compress, it does not appear to be (spherical radius + the knuckle radius)/2, nor (spherical rad. + 2*the knuckle rad.)/3.
When the Code does...
I am having trouble correlating a value for 'A' given by Compress and one looked up (and even interpolated) manually when calculating a shell and ellipsoidal head for external pressure.
I was wondering if anyone knows how Compress finds this value? I would assume that the method used for...
