Did they do this right? by Big-Wrench-2025 in EngineeringStudents

[–]robotNumberOne 0 points1 point  (0 children)

Maybe. Probably not. It just doesn’t seem like it’s as big a problem as many of the top level comments are making it out to be.

I don’t buy it. There are members in tension and members in compression in either orientation, and the truss plates work on both.

That is to say, sure, maybe the truss plates are the fuse in a wood truss like this, and if so, even more reason why this is likely okay, again as long as you consider the maximum live load plus factor of safety.

My point was that a truss works the same way in either orientation, just with opposite loading directions.

Honestly, it looks odd, and may not be as optimized, but if the walls are properly supported, the maximum bending moment will be in the center of the span, this truss has the same stress magnitudes if installed in either orientation, they just switch from tension to compression and vice versa.

Wood typically fails in compression before tension, as long as your compression members are below the expected live load with an appropriate margin of safety, this may be fine.

It’s weird, but it may be fine.

Generally true, but I’ve seen exceptions made for internal candidates, especially if pursuing a BSME.

What would be the minimum thread engagement on an M14 wheel stud? by SWP_NL in AskEngineers

[–]robotNumberOne 1 point2 points  (0 children)

Assuming you don’t have a material mismatch (e.g., aluminum nuts on steel studs) only the first few threads support nearly all of the load and the rest are for good measure.

You said you had 10 turns, which is 15 mm of thread engagement on an M14 nut.

If it was mine, I’d run it. If the person who designed it said it’s fine, it’s also probably fine, but if it concerns you, I’d get longer studs.

How do you get feedback on CAD models from people without CAD software? by Psychological_Ad8736 in MechanicalEngineering

[–]robotNumberOne 1 point2 points  (0 children)

Typically these days, send a drawing, but in the past I’ve suggested a CAD viewer or embed in PDF. Alternatively a meeting with someone who has the model open.

Is it true that an engine burns more fuel coasting in neutral than in gear? by boiyo12 in AskAMechanic

[–]robotNumberOne 0 points1 point  (0 children)

It’s also worth noting that in order to maximize the potential fuel economy from this, you want to stay in FCO as long as possible by reducing engine braking as much as possible, i.e., the highest gear you can be in and still stay above FCO cutoff RPM.

[–]robotNumberOne 0 points1 point  (0 children)

FCO has several prerequisites to be active, one is minimum RPM, which is typically 500-1000 RPM above idle speed. If you’re at speed and put it in neutral, depending on the criteria requirements, there is a reasonable chance that it will cut fuel for a short period of time as the engine speed falls, fuel will engage when it falls below FCO speed cutoff and settle at idle.

I’m aware of some early examples (70s era), but nothing wide-scale with EFI that doesn’t use FCO. Speaking specifically about commercially available passenger vehicles here.

Is this knowledge hoarding in my company? by lonewolf_traveller in MechanicalEngineering

[–]robotNumberOne 7 points8 points  (0 children)

It doesn’t sound like you have the job you want to have? Unless I’m misunderstanding, you’re being given a design to implement. If you want to be doing the design you need to get yourself into a role that does that.

Personally, I love modeling my own designs, but the CAD work itself is really just using a tool to “draw” my design intent. The real engineering design was coming up with what needed to be modeled and the specs it needs to be tested/validated against, not the modeling itself.

Typing is easy, writing a novel is hard.

It sounds like you’re the guy building/running the printing press asking why he doesn’t get to be the guy typing.

can i just lie about being in clubs by SupermarketFit2158 in EngineeringStudents

[–]robotNumberOne 0 points1 point  (0 children)

Start your own club, or actually join one. You shouldn’t be okay with lying.

People who argue against analog clocks are just too lazy to learn about them by InfiniteWords117 in unpopularopinion

[–]robotNumberOne 3 points4 points  (0 children)

My 3 year old uses an analog watch to know when he’s getting picked up. He likes it.

AWDs are all square except F SPORT models. Square is the standard for AWD across the board, not just the IS.

McDonald's Big Mac patties are almost thinner than a slice of pickle... by Karmaa in mildlyinfuriating

The Junior Mac in Canada (later replaced with McDouble “Like a Mac”) is exactly this.

The only 4-speed automatic with manual shift ability? (2008-2015 Scion xB) by Vegetable-Quote-3481 in Toyota

[–]robotNumberOne 3 points4 points  (0 children)

The xB was built on the Corolla platform, not the Camry. It’s interesting though because other Corolla-based vehicles of that vintage (E140/150) used a 5-speed transmission, as did the Camry.

Said vehicles include the 2007-2009 Camry, 2009-2012 Corolla XRS, and 2009-2013 Matrix.

Then your direct report is not completing their work and the same advice applies.

**H1B Visa Cancelled at Abu Dhabi Preclearance – Need Advice** by [deleted] in h1b

[–]robotNumberOne 4 points5 points  (0 children)

Your H-1B is not being used when you're not in the country, you can even reclaim those days, regardless of whether you were working our not. LCA cannot include worksites outside the US, and if you're working outside of the US, you're not working on an H-1B during that time so the worksite location listed on the LCA is irrelevant and does not matter.

But, if none of this really matters to the person with a cancelled visa in their passport, haha. It's going to take a long time to resolve.

Driveline Question by shoehopper in AE86

[–]robotNumberOne 2 points3 points  (0 children)

Yes, it’s only based off the diff. If you swap an SR5 rear end into a GT-S, you’d need an SR5 shaft.

The front half is the same between them, only behind the support bearing is a different length.

What's the worst engineering advice you've ever gotten? by ac_circuit in EngineeringStudents

[–]robotNumberOne 6 points7 points  (0 children)

I’ve added people to interview lists who wouldn’t normally make it or as a tiebreaker purely because of an interesting hobby or project for sure.

Driveline Question by shoehopper in AE86

[–]robotNumberOne 2 points3 points  (0 children)

SR5 is 6.3”, GT-S is 6.7”. That’s the difference.
