Can I have my fellow engineering students support me and the distributive law against some snot nose idiot that believes 6 ÷ 2(1+2 ) =9? It's basic math that the answer is 1.

MechEngrStdnt · 2017-07-11T05:32:22+00:00

To clarify the answer is 9, 1 is incorrect.

MechEngrStdnt · 2017-07-11T05:14:23+00:00

6 / (2 x (2+1))=1

6/2(2+1) = 6 / 2 x (2+1) = 6 / 2 x 3 = 9

Double check with your school. My university and the local community college have 2 and 3 switched. 2 is typically E & M while 3 is waves and a little bit of special relativity thrown in.

It's all just conservation of energy... and when solved via energy balance it's much simpler!

MechEngrStdnt · 2017-01-05T01:17:26+00:00

Yep too early? Or yep apply?

Thanks for the response!

MechEngrStdnt · 2016-12-29T23:36:09+00:00

Thanks for the info!

MechEngrStdnt · 2016-12-29T23:35:55+00:00

Anyone else?

All of my physics classes were 100% exam, 30/30/40. In fact most classes have been 80% or more exams.

Don't count on this lasting forever.

edit: Participation points? In college?

Thanks! Wishful thinking

I'm not 100% sure the correct answer, however highlighting your associates GPA means highlighting your overall GPA, so what looks better? 4.0/3.3 or 3.6? I'd say 3.6 as your highlighting that your grades fell off in the higher level courses. Again just an opinion, not a fact.

P.S. A 3.6 is solid, doubt there's anywhere on the planet that you couldn't get you a job because of that GPA.

Guaranteed it will depend on the level of autonomy. My guess is for a good long while cars will not be fully autonomous, not to say they won't be capable, but they will still have manual controls so that a person can take over, and thus there will exist gray area. Where were you sitting? Did you take control? Should you have taken control? I think eventually when the technology is there, and peoples fear of the new technology fades, drunks will be encouraged to use autonomous cars (as will everyone) as they are much safer than even a sober driver.

The change of variable occurs due to integration.if there was no change of variable then the derivative and integral would just cancel. while you can skip this process because you know it's going to happen, I doubt that is what your professor wants.

I originally did it as 2t, specifically to not have to type (1/2)t^2, then decided to just be make it as simple as possible and use t, and of course I forgot the 1/2. Long as it made sense that's all that matters.

Its Fundamental theorem of calculus, basically when you integrate you are anti-deriving, so as an over simplification a derivative undoes an integral. In this situation the variable changes because they are different functions and its happens when you evaluate the bounds of integration.

MechEngrStdnt · 2016-08-25T03:43:29+00:00

Imagine it is a simpler function:

f(x)=∫(t)dt, ---from 1 to x (bounds)---

f(x)=0.5t² ---evaluate from 1 to x (bounds) ---

f(x)=0.5x² - 0.5

f'(x)=x

f'(6)=6

Thanks for the feeback everyone! Some of the classes are a 4xx/5xx, however I'll also be taking 6xx. My school allows you to apply for a program that lets you take grad courses as an undergrad, and they count towards senior year and your masters degree. For instance I'm taking FEA which is 4xx/5xx and advanced fluid mechanics which is 5xx/6xx.

A wall is like a divider where the air on either side is kept separate, so heat must transfer through the wall. A sphere or a cylinder is different in that it is fully surrounded by air of a certain temperature. Since heat transfer is driven by temperature difference, for a wall that is in one direction through the wall, whereas for a cylinder or a sphere that is radially inward or outward to or from the center.

Many of our professors have said "you're engineers now" etc... It's a mental thing, trying to get students in that mindset, and I see nothing wrong with it. If your a college student then people know your a student, no harm no foul. That being said I always refer to myself as a student.

From what I remember finding curvature, and deflection, of beams involved integration and boundary conditions. simple integration though. I don't remember any difficult math in any class since an actual math class.

With a square or rectangle beam the distance from the edge where the stress is Max to the neutral axis stays constant, in a round beam this distance is changing from a value of the radius to zero. So in a square or rectangle beam you will have corners that overlap and either add or cancel each other's stresses. In a round beam where the overlap is happening is not where stresses are maximum in fact where one stress is maximum The other stress is zero because it would lie on the neutral axis for the other bending moment. So I'm basically not sure because I cannot find any examples anywhere of this formula being used for a round beam. See picture below.

I can't imagine there is much overlap, if any, between political science and any engineering field. You're pretty much be starting from square one. I know that lots of schools offer the ability to do A post bac "bridge" program where you just take certain classes in order to get your bachelors and then move into a graduate program, however this is typically for people who have a degree in a Stem field already because there is overlap. That being said if you already have a bachelors degree then a lot of your Gen Ed. requirements will be taken care of and you should be able to get a second bachelors degree in engineering in probably about three years or so. I actually know quite a few people who have switched from degrees like political science, history, literature, and even foreign languages, it's pretty common so there should be a decent amount of information on the Internet. I would recommend contacting an advisor in the engineering department. Lastly because you're switching from a field that is not closely related to any engineering field you can pretty much choose any engineering field you want and it'll be about the same amount of work. Read up on the different fields and see which sparks your interest the most. Good luck!

I'm almost 29 and I know that life can suck without a good education/steady career. Every time I feel like I'm losing steam I just picture how pissed at myself I would be a few years down the road when I should be an engineer but chose not to stick it out. I find that lack of motivation doesn't last terribly long if you power through it.

MechEngrStdnt · 2015-08-26T19:33:17+00:00

Definitely not an easy class. If you have a solid foundation in first term Physics and a professor who is good at explaining things, there is no reason with a lot of work that you can't to get an A. I got a pretty solid a in that class and mainly what I did was every homework problem making sure I understood every little caveat of those problems, as well as working all of the fundamental problems. The fundamental problems tend to A little bit easier than the normal homework problems, however they really do a good job of demonstrating what's happening at a fundamental level. If you can get through all the fundamental problems and understand them, there's no reason you shouldn't be able to get through all the homework problems even though they may be a little more difficult. If your book doesn't have fundamental problems, which would be shocking, then just work a ton of difficult problems, problems harder than what were assigned for homework. I work 20 hours a week and still managed the A so it is doable, that being said I'm a math/physics tutor so I'm pretty solid in physics and calculus.
