I'm reading the comment section to a shitty article about how the shortage of native engineers is bullshit.

I came to this post:

"In my opinion, which is backed up by being a professor at a US engineering school – foreign students are sought after because they are typically much BETTER prepared when they enter graduate school – not because they are cheaper to have as graduate students. Although some professors may depend on a foreign student accepting working for no pay just to be in the US, most offer stipends and tuition waivers to these students in exchange for working on projects."

How does this comment make you feel?

My first thought is "has this professor thought about why foreign students are better prepared? And has he taken any action or responsibility in better preparing his native undergraduates."

in my experience international students are exceptionally hard working students but tend to be depressingly un-innovative

to be fair innovation is rare these days

most engineers do it for the degree and just grind it out

i feel like innovation is more common in the software and electrical engineering degrees but the by the 4th year the innovative types either commit suicide or drop out and find a programming job at some startup

too bad you can't measure innovation in a report card

actually that happens in the west too, just not in the US from what I gather.
Universities in europe are often theoretical and can be hard on engineering students, for example it's absolutely impossible to work and study unless it's a part-time program.

ITT: engineers proving they have zero people skills and getting butthurt over semantics. I knew what a transistor was and had learned 2 programming languages before I graduated from PUBLIC high school. Would I have made a good engineer of any sort? If this thread is any indication, then hell no. You know why? I can't stand people who are so close minded. Everyone in this thread is obviously biased from personal experience, and all you can do is insult each other for it. Do you all really feel so threatened by the prospect that another, more experienced engineer has the right answer? I guess so, otherwise you wouldn't assume anonymous to be an underage high school dipshit all the time.

Hi /tesla/

24 year old employee of an engineering company in the defence sector. At the moment I have an HND in Electrical/Electronic Engineering and after this year will have an HND in Mechanical Engineering. I'm looking to top this up to a degree in Mechanical Engineering (currently doing all the UCAS bollocks) starting this September.

Any UKfags here able to advise on the best universities, experiences with applying with different qualifications, etc etc.? Also, as an older student does anyone have any experiences of this to share. Should be noted I also have A-Levels in Maths and Physics (they are poor grades, E and D respectively - I wasn't so committed at college but like to hope any University would take into account my two Higher National Diplomas.)

I know Bristol, Bath, Manchester are pretty good for Mech Engineering.

Thanks all!

Hey /tesla/, just hoping you might be able to offer some advice.

I will be applying to study engineering at uni in the near future and heard that programming is taught as part of many engineering courses. I have no previous experience of programming and thought it might be useful to gain a basic understanding of a language before I apply, as it could boost my chances of getting an offer as well as making the course slightly easier. However, I know that CAD is also important for engineering, especially mech.

My question is would my time be better spent learning a language such as MatLab or learning to use a CAD program such as Solidworks? Bearing in mind I will be doing a general engineering course so will cover most of he more traditional disciplines. Also, which language/CAD program would be most useful/easy to learn? I would love to do both but currently don't have the time due to a work and school.

tl;dr Should I learn a programming language or CAD for a general engineering course, and which language/CAD program?

Thanks in advance and sorry for the wall of text.

Currently in my 3rd yr of a general engineering degree. We've used MatLab and some other languages as well as Solidworks and AutoCAD and a few other tools. I think we got around 10 hours of labs for both MatLab and Solidworks in my first year and that's about it. The philosophy is that the course isn't aiming to teach you how to use those tools but giving you a favour of what tools are out there and what sort of things they can do in order to aid you to solve a problem. Ultimately, we have complete freedom over what programs we use, or if we do things by hand.

The most important skill I have developed is how to RTFM since it's likely I'll be using a piece of software for a single lab (one 6 hour day) and won't ever touch it again.

So I am designing something for a friend. I am not very far into my basic of basics electric circuits book, and I've hit a wall. The device itself is very simple, just 2 CDS cells acting as a voltage divider. I want to take a snapshot of the voltage output...say every 100ms and be able to plot this over time

I haven't the slightest clue where to start with logging the data and being able to plug it into a computer.

The end user is basically illiterate in these things, and I want them to be able to see what is happening with the device, without them getting frustrated.

I have about 4 months to figure this out.

Why two CDS cells? Are you trying to compare the brightness in two different areas? I think you would be better off putting them in a wheatstone bridge either way.

As far as logging the data, your best bet would be something like an Arduino Uno paired with the ethernet shield. If you've programmed things before, I'm sure you can figure it out in 4 months.

Shipping containers are stackable, waterproof (for rain, not for dropping them in a river), and strong. They also cost around $15,000 new. I heard about a guy who built a small underground shelter using a shipping container that he buried in his backyard, and I was thinking about trying this myself.

I can get 6 carbon-steel sheets, half-inch thick, and weld them together myself for around $6,000 (before shipping, ironically). Would this plan work, or am I missing something crucial?

>>5936 there is a reason im not a engineer... i dont even know where to start researching.

i was looking at rigid 2 inch foam insulation, specifically http://www.homedepot.com/catalog/pdfImages/4d/4d258498-d60f-412a-bfe5-f3ad7e813c00.pdf. now i see r value of 10.8. then i tried to figure out exactly what that means. i got to this formula " hr•ft^2 •°F/Btu (RSI, °C•m^2/W). i know what everything up to the parentheses stands for.... but tbh.... even if i figure all that out i probably wont understand it.

basically im trying to figure out if my house is at 68 inside and its 10 out side how long before i have to turn the heater back on if i got 2 inch insulation. and this would help avoid the tin oven effect some what right?

according to my knowledge of thermodynamics, it is not possible to be calculated with the data you are giving us. we would have to know the area of the container (not the width*height for all faces, but the actual area of the bended panels), this means it is going to matter if you put your insulation on the inside or outside. I would also have to know the thickness of the steel plating.
And assuming you want to keep the temperature at 68F, we would have to know how much heat your heater can produce.
if you want me to calculate your shit, give me the area in m2, the plate thickness in mm your temperatures in K and your heat production in Watts.

I'm doing a little project of mine and I have encountered a problem..

The project is basically a motion platform that moves in three directions at very low forces (few mN). I got the first two direction done (X,Y), but the third is giving me trouble due to the gravitational force.

Basically I use some very thin beams (flexures) that allow deflection in one direction and none in all others. In X and Y I have no issues with gravity, but in the Z direction the beams own weight and as the force is not applied directly at the centre of the flexures, my whole thing starts to rotate which I don't want.

So I was thinking of maybe using a linear spring that doesn't allow bending.. Do such springs exist at such a stiffness (20 N/m)?

Hey guys

I'm currently in first year and for a chemistry based unit we have to figure out what
material 9 components are made from. Most metalic, some polymer.

Anyway i'm not entirely sure when it comes to moter mechanics, and was wondering what some of the components will experience, in-terms of stress, heat subjection, and basically any condition that would applied during use.

Things like the cylinder head, the crank sump case, the crankshaft, the piston and the muffler.

The polymer components, i'm assuming, won't come under much change in temperature but conditions more like stress.

TL;DR - What parts of a 2 stroke engine for a chainsaw would experience high temperature? What defines the properties of the materials used?

I wasn't sure where to post this, but I figured you guys would be most suitable. I'm a pro wrestler and to make my appearance more interesting I'd like to wear a flamming jacket during my entrance. Something like pic related.

I'm no engineer (philosophy student pls), which is why I seek your advice to build such a thing. What I would need would be some sort of trigger that activates the fire on the back, be it on the wrists or even on the chest, and the fire would need to extinguish after ten seconds or so. Again, forgive my ignorance, but I imagine the jacket would need to be constructed in 3 layers, the first a protective material to prevent burning and pain, the second an absorbent material which could be dosed with a highly flammable liquid and the third would be a metal that wouldn't conduct heat yet would allow the fire to seep through, maybe in the form of chain-mail. It may be safer to just have the arms light on fire. I was thinking maybe just altering the arms on a greatcoat but with the same premise as above.

Any advice would be a great help.

And use a "stage flame", a low-temperature alcohol flame that's less likely to make you into a crispy critter.

And you should use some version of this as your entrance song.
