"hands on experience" and "machining skills" is good advice if he wanted to become a mechanist. If he wants a head start he should start learning a useful programming language or self-studying calc/thermo i.e. "book smarts". Anything you could possibly do practically before being at least two years into degree (internships etc.) would be absolutely worthless to his engineering career.

>> No.5378923

You need to be able to visualize a system. Free body diagrams are crucial, but the kind you learn in basic physics classes only go so far. Read up on statics and dynamics. There are also some videos on youtube.com/MIT and youtube.com/nptelhrd that you could watch to get a feel for it.
Differential equations is pretty important, but it's also about using complex analysis and linear algebra to make your differential equations tools more accessible.

obviously you have no real world engineering experience. Computers do all the simulation/math for you. What is actually needed is a good understanding of what can and can't be built. As well as the cost/time to built parts. All things a machinist would know and which would be useful for an engineer to know. Alot more useful than integrating by parts and all that other calculus nonsense.

Yes, and you need to understand the math to write/use a program. Computers don't "do" anything for you, it's just a tool.

>What is actually needed is a good understanding of what can and can't be built. As well as the cost/time to built parts.

Not really, maybe for the 0.5% of mechanical engineers that will work in a relevant industry, but most won't.

>Alot more useful than integrating by parts and all that other calculus nonsense.
You don't seem to understand the point of learning analytical integration, it's needed to understand higher concepts in Calc that ARE needed if you want to be a (real) engineer.

Depending what field you are in, the man has a point. An aerospace engineer doing CFD for the F35 needs to know partial differential equations, etc. A design engineer at a company making mechanical devices needs to know things like GD&T (an important skill but one that doesn't require heavy math). Those sorts of jobs are where practical skills trump theory any day.

>Those sorts of jobs are where practical skills trump theory any day.
1 - He can get those "practical skills" on the job easily, in fact, the AeroE will need to learn a lot on the job before he's useful too.
2 - He still needs to know Science and Engineering Principles, the fact that he will be better at this particular job if supplemented with practical skills is irrelevant.
3 - Telling OP to "get hands on experience" -which could only possibly mean technicians work (because everything else requires an engineering degree) - and "machining skills", OP probably obviously hasn't even picked a specialization yet (or he would've specified), so it would be a waste of his time (that could've been used mastering PRINCIPLES) if he decided on a different career path.

>Should have learned them in fucking school so his job doesn't have to hold his fucking hand the first 6 months. This is why no one wants to hire newbie engineers.
No, FFS, we can't learn everything about every little goddamn niche industry in the world.
You learn Principles that you can apply in any industry, you learn everything else you need to know on the job (which will be easier and faster since you understand the Scientific and Engineering Principles behind them). What the tripfag was talking about is only relevant in some industries, ones that OP might not even be interested in, the confusion arises because of >technicians/draftsmen/machinists etc. calling themselves "engineers".

>You're an idiot.
Maybe you missed the point behind the statement, it IS irrelevant; until he decides to specialize in a relevant industry then his practical skills IN THAT industry becomes relevant.
It won't help him to know machine turning if he decides to go into nano/mat sci R&D for example.

The point of engineering education is to learn enough background knowledge/skills to apply to a whole variety of problems. Essentially, learning to learn.

OP focus on those freshman/sophomore engineering classes, especially statics, dynamics, calc, DE's, thermodynamics, circuits. Mech engineering has a million applications, so you need the background.

Practical engineering and R&D engineering are a completely different kettle of fish.

Ignoring your arguments you're being a shouting cunt for no reason so calm the fuck down.

If you're meant to be out building something somewhere no one will expect you to be whipping up a differential equation to solve because that work should have been done before the job is started. Basic trig and geometry will suffice.

If you're in the office and you actually have to do something complicated your math will suddenly become useful. I don't want someone designing the wing of my plane if they don't know how to integrate pressure over a surface "but the computer told me to do it that way".

Theory is much more important than workshop skills if you want to work on the best projects. Jets & racecars aren't made without maths.

Kindly STFU and appreciate the work other people need to do that lets you get on with yours. This applies to both office and field workers.

Part of the job. Boohoo you have to do a little bit of thinking to cut something up a little, deal with it. Not every single problem you might run into can be accounted for and predicted, even by someone with experience and especially if they have a busy workload.

Practical experience would be a bonus but when you're full time at university you don't have much chance to get that experience. If you're working with inexperienced engineers then help them help you by explaining to them the correct or better way about something instead of just bitching.

My research deals with some aspects of the curvature of a Riemannian manifold, in particular the way various curvature assumptions influence the topological properties. There are several groups of theorems that address this question, and my contribution belongs to Pinching Theorems. The method I used consists of studying special flow of metrics whose property is that the reduced curvature tensor changes according to the heat equation.

I have also employed the tools of Riemannian geometry (especially foliations on Riemannian manifolds) in order to study the properties of orbits of vector fields coming from various control theory problems.

In collaboration with two colleagues, I have obtained new parametrization of the space of multivariate normal distributions (and a new distance formula) and am investigating further applications.

And that's why you, and people like you, will never be a good Engineers. Quite simply; you're followers, not leaders. But hey, at least your company will have some monkey to sign of on more competent engineers' designs.

>>5379454
Yeah, no, I've been fixing engines with my dad, soldering, wiring and welding since I was ten, nothing technicians do is difficult, it's just -slightly- skilled hard labour (and I respect them for their hard work, not the knowledge they which is easily obtainable), why don't you just shut the fuck up and go sit in the corner.

>All I did was give advice to OP

>Any respectable math teacher will tell you that 90% of calculus is useless.
What you mean the introductory stuff? Obviously, you'll be using numerical methods to solve problems with algorithms written by Engineers much smarter than you, but those programs are useless if you don't understand the theory behind them.
Also
>90%
You seem to like using that number when you're about to spout bullshit.

>You seem insecure since you felt the need to get on your high horse about being an engineering student so therefore claiming your opinion is more valid.

Can't believe you think small problems within manufacturing like this is even related to engineering. As for how the rest of the thread played it, the fault lies first in you because you did not clearly define the problem. This is typically due to a lack of communication skills and you really need to improve on that if you want to become an Engineer. Futhermore calc 3 Professsors aren't impressed with trig. so you are probably lying about that and none of the answers given in this thread is correct because you gave 10 sig. fig.s when you were only allowed to used one. An examiner in an engineering school would give you nought for that answer.

>>5379777
Even this better advice than the tripfag gave, at least you learn problem solving skills and information competency that can be applied elsewhere.

>>5379870
Solving book problems (specifically in engineering texts, not the "problems" in calc./pure science texts) help develop invaluable problem solving skills, go ahead and try to get someone to design a reactor without first doing the easy problems.

>>5379887
NO YOU GAVE SHITTY ADVICE, YOU'RE A FUCKING SOPHOMORE, YOU HAVE NOT EVEN PASSED ALL THE INTRODUCTORY AND PURE SCIENCE COURSES YET, YOU HAVE NO RIGHT TO GIVE FUTURE ENGINEERING STUDENTS ADVICE. AND YOU'RE STILL USING IMPERIAL UNITS LIKE A NOOB.

I going to start mech engineering next year, and both pratical and book skills SOUNDS good advice, I know I still have a lot to learn but my common sense tells me BOTH are important at least to some degree, of course I don't need math of a fucking real math major, and I don't need the same skill with machines then the fucking head mechanist.
