    Planetary Telescopic Bicycle Kickstand

    Definitely a neat idea, a kickstand that retracts some length when raised is definitely a "would be nice." However, in all my years riding bikes, the kickstand being too long and catching on something or accidentally deploying has only happened maybe 10 times, and could be fixed with a kick...

    Some scientists have an idea to bui

    I agree with Choras. Have you seen the cost of unobtainium these days? Not to mention it's a nightmare to work with.

    ASME BPVC.VIII.1-2023 Man App 2. Flange Connections Calculations

    The wording "should not be less than" seems to be there because normally allowable stresses are maximums you can not exceed. In this case, because we are designing the flange, the strategy is inverted when regarding bolt stresses. Bolts could theoretically be stressed to Sa, so your flange must...

    ASME BPVC.VIII.1-2023 Man App 2. Flange Connections Calculations

    ...you are essentially taking Am and Ab, which is Am + extra_area, you end up designing your flange to withstand an additional stress: extra_area/2 * Sa. You are correct that it's not "consistent", but does it have to be? 2. That clause is to prevent damage to the flange by designing it as if...

    UG-34 ASMEVIII

    Understood. Then yes, UG-34 is a pathway. Just to note, often UG-34 requires thicknesses above those of B16.5 standard flanges, so it may not be sufficient based on your design pressure/temperature. I don't have access to COMPRESS right now, but it may allow the calc if you remove the B16.5...

    under what situation, the creep analysis is mandatory?

    You should be concerned for creep at temps around 50% the melting point of the material. However, as you have pointed out, allowable stress values already account for creep at these temps, and thus there is no code requirement for analysis for Div. 1 vessels. Creep analysis is only useful if...

    Modeling fittings acc. to ASME B16.11

    Going off of "G" should give a fine result. Unless you have hundreds of these in a line, the minor thickness differences should be negligible. Just don't forget to enable SIFs for socket welds as per ASME B31J (if applicable to your code):

    UG-34 ASMEVIII

    Why do UG-34? Is this a custom blind? It looks like you could do a studded outlet with a standard B16.5 blind, in which case no UG-34 calc is needed (see UG-34(c)(1)). As for your question, I assume you are confused by the joint efficiency. See UW-12(d):

    What do all the useless engineering graduates do for work?

    I struggled to find work for months after I graduated. I had work experience from three student work positions, so I wasn't entirely green, but I still struggled. Two of the student positions were at sites that closed down, and the third was not hiring, so I entered the rat race of resumes and...

    Two-slider crank mechanism

    The least any inventor could do is a mockup CAD model. Autodesk has a program aptly named "Inventor" you can use for free (non-commercially). Even if the dimensions are not "correct" without detailed analysis, a 3D model would get people to understand and appreciate the concept more.

    Overriding the layout to be more compact, or any other changes

    I really like this. I tinkered with it a bit and was able to change out some colors too. Here's a green look to match the Eng-Tips icon .p-nav { background: #1e9646; } .block .block-minorHeader{ background: #1e9646; } .p-body-sidebar .block .block-minorHeader{ background: #1e9646...

    Firm Recruiting Engineers to Train Generative AI Models

    I don't see anything inherently unethical in verifying an AI model as long as its training data was provided with consent and the verifiers are qualified. I think people are right to question the use of the AI model after the fact though. It is up to the end user to act ethically, but that's...

    Instruction for managing new Thread Notifications and Accessing your watched forums

    Exactly. The side bar showing all my followed forums, each bolded when updated, was perfect. It was 1 click to get to new posts. Now I have to click 3 times, and cannot view a post while doing so — It's a new page each time, which adds 3 loading screens (which are also slower now, at least on my...

    Exclude some load cases in envelope?

    It sounds like you may want to transfer your data over to a spreadsheet. That way you can add the data for every LC and filter them as you see fit. I don't know why exactly you want to exclude certain cases from the envelope. Non "control" cases like 0.6D±0.6W are for checking sliding and...

    UW-20 for U-tube HE

    Same statement does exist in Div 1 2023 ed. UW-20.1.1(d) "Determination of tube-to-tubesheet joint strength is not mandatory for U-tube construction."

    Exclude some load cases in envelope?

    It sounds like you want to use "Batch Solution of Marked Combinations". This will solve all marked LCs, and it allows you to toggle between the filtered envelope and the entire LC batch:

    ASME Auditor/Inspector Validate Software licenes copy

    You should have your own copy. That is more of a legal issue though depending on ANSYS terms of service. Audits will usually look at the broad strokes of what you do. They may ask what software you use and leave it at that. I find client run audits will even ask for your validation of software...

    ASME CODE STUDY STRATEGY.

    Idan is absolutely right. Reading the code front to back, though not a bad idea, will not grow understanding, only familiarity. You should approach the code in context of problems needing answers. Find somebody experienced with the code and ask them for a sample of the calculations for a vessel...

    An ASME interpretation regarding UW-11(a)(5)(-b)

    UW-11(a)(4) does not apply: the nozzle thickness does not exceed UW-11(a)(2), and is not attached to head and shells falling under UW-11(a)(1),(2) or (3). UW-11(a)(5)(-b) states: "Category B or C butt welds [but not including those in nozzles and communicating chambers except as required in...

    Regarding Overhead Beam Capacity Tag

    Loading the very end of the beam is also worth checking, as that will maximize loading at the beam connection there. Personally, I would check the crane at the start, middle, and end of the beam. If things are broadly symmetric then checking at only one end and at the middle should suffice...
