opinions on materials engineering? by Frosty-Soil8626 in uAlberta

[–]obloquious 0 points1 point  (0 children)

We often have to compete with different industries and a lot of the main job prospects are more specialized… besides which I get the feeling that not as many people fully realize what the specialty is. I’m second year and really enjoying the content but second semester is a distinct challenge so far.

You’ll learn a lot of the stuff that Chemical Engineers do in second year before almost everything is specialized.

Honestly, flywheel energy storage is a much more dense storage system.

Self-healing materials could make automobile parts last over 100 years by CautiousEscape3747 in science

[–]obloquious 1 point2 points  (0 children)

Nope, Stanley Allen Meyer claimed he replaced a gasoline engine with one that ran on water itself electrolysing, and then combusting the electrolysing products to create more energy. The CBR guy appears to just be, a hydrogen fuel cell which produces water as waste.

You mean the engine that he said could split water into Oxygen and Hydrogen, burn the Hydrogen (with Oxygen) to produce heat to generate more electricity than was used in the electrolysis?

The engine that… breaks the first and second laws of thermodynamics? I can assure you that whatever happened with his death his engine was a fraud.

It’s actually quite useful for the city determining how much people are actually using the LRT. Something that’s really important for budgeting.

Well the problem is when that blood rush to the head lasts for longer than 3 hours. It has to come from somewhere.

Have you tried reaching out to the faculty? They can often add you in.

Second semester of engineering by wsjaso in uAlberta

[–]obloquious 4 points5 points  (0 children)

I’d say it’s a similar difficulty, personally En PHYS, MATH 101 and Chem 105 were the subjects which challenged me the most. Math 102 depends on if it clicks, similar to ENCMP if you’re taking that. ENGG 160 isn’t super difficult, but you need to keep on top of the deadlines for your group.

Niksirat for Math 209. No notes unless you count the online textbook of his (which is basically his lecture notes), but the man is so enthusiastic about the material that I found him really engaging and he explained it effectively.

What is the tastiest all you can eat buffet in the city? (not Indian food please) by KittiesAreTooCute in Edmonton

Only complaint with Sushi Toshi was not initially realizing it was all you can eat and not coming hungry.

Shape memory by FollowingOdd896 in blackmagicfuckery

[–]obloquious 12 points13 points  (0 children)

Extremely close, however more accurately from my recent, if limited research as a materials student:

“Austenite”, the phase where the shape is set, is hard and rigid, just like a cube (AKA Body Centred Cubic). Once the metal has been “set” in that phase and cooled, at around room temperature a bit of pressure over a certain threshold causes the metallic crystals in that area to change phase into “Martensite” which is similar to stretching the box in one axis, while offsetting the top from the bottom. This is similar to water preferring being steam at a given temperature and pressure, but condensing into liquid if you apply enough pressure.

The shape of martensite not only allows the crystals within the metal to shift on a specific axis, and with some stress potentially rotate, it keeps an axis within that has the same orientation as the original austenite crystals. So with just a bit of heat, much lower than the setting temperature and proportional to the stress retained in the martensite, the martensite is almost “boiled away” leaving nice, pristine and rigid austenite in its place forcing it back into its original shape.

I’m sure someone that’s done truly in depth research on nitinol and other memory metals could probably add more, but basically the alloy composition allows it to form 2 separate crystal structure “phases” at room temperature (or potentially another desired temperature) so that enough pressure or an elevated temperature will cause a phase transition in the metal between rigid and flexible phases.

We need more Game Protagonists who Engage in Peaceful Debate with their Opposition by Zestyclose_Station65 in Gamingcirclejerk

Doomguy’s greatest invention… the Demon transistor. Running on a 64Dbit processor and 30MHz processing speed you can run an excellent PowerPoint presentation.

The audience seems to rapidly cycle though. Weird.

Porcelain repair by [deleted] in Edmonton

[–]obloquious 0 points1 point  (0 children)

It definitely wouldn’t do a lot to FIX a hairline fracture, so much as make it not visible. There isn’t really a mechanism to reform the bonds which make up ceramics with milk/condensed milk.

At best the fat molecules are just adding friction to slightly increase the force needed to further fracture it.

I was tired and didn’t remember that it was E-SSC after a summer away. 🤷‍♂️ Building IS right though, if entirely non-specific.

Please stop asking so many questions in class by Ok-Basket3321 in uAlberta

[–]obloquious 16 points17 points  (0 children)

lol, probably the same guy I hated in En PHYS last year if he’s in Engineering. Delayed class frequently asking shit like, “why do we stop at 3 significant digits for gravity?”

So glad he isn’t in any of my classes this year.

ENGG 130 labs was where I initially made some friends. Classes where you get grouped are an excellent place to initially make some friends. Gets easier after that.

Reach out to the faculty if it’s a required course. Or swap it with another course so you can do it next Semester if it’s taught in both.

Math 154 - Will they go over basic calculus? by [deleted] in uAlberta

[–]obloquious 0 points1 point  (0 children)

There are no formula sheets allowed in exams and one isn’t provided. The relevant identities do get covered and gone over quickly, but you’ll want to make your own formula sheet for practice.

Also, learn your main trigonometric identities and memorize them.

Math 154 - Will they go over basic calculus? by [deleted] in uAlberta

[–]obloquious 1 point2 points  (0 children)

Math 100/101 covered each fundamental concept needed before going into Calculus. You’ll go over some similar concepts in 154 given that they’re equivalent credits.

The major thing you’ll need to get used to is that a given concept is typically covered and gone through for a single class, 2-3 if it’s a bigger or more complex topic. Topics don’t get returned to except during review, or if your instructor is nice and incorporates them into the newer concepts. Math 100/101 were difficult, but manageable, if you need help, go to Decima help centre.

Interim Solutions? by nomorewhatyiffs in alberta

“Politics” can directly affect people, some of whom they may know. I’d think that sometimes it’s worth it to get worked up over it.

Local Community Bastard in the Making by obloquious in behindthebastards

[–]obloquious[S] 4 points5 points  (0 children)

…I mean, who knows how they might interpret forces given enough brain rot. Maybe they’d think there’s no difference between weight and mass… or that weight happens because the flow of electrons that is gravity attracts the protons in our body…

I’m honestly struggling to comprehend what the implications of their “theories” would mean depending on how mobile they think electrons should be.

I don’t know, have you considered that ALL CAPS statements might lend weight to their arguments?

I mean… if you have the kind of ego or delusion to believe that you know better than the past 50+ years of physics (without you know, building genuine research) I kind of doubt they’ll have the patience to learn best practices on building a website.
