reinforced concrete, yeah...

Sure, physics can jump into just about any engineering field, in particular civil and mechanical.

hmm well that sounds great then. Does anyone know what it's like to be a field test engineer person, who services installed stuff? That sounds like It'd be cool, to be jet-set and learn the biz. That or, with my awesome writing skillz act as a gobetween with the business side of things...

Get a geotechnical engineer to design the bulk of it, and maybe a structural engineer if needed.

Watch Grand Designs.

You know what would suck? If it rained and the drains clogged.

>you put wheels on a coffee maker. congrats.

Coffee makers don't make very good tea. Trust me, I've tried it. You need to boil the water first, and let it cool a little, before you add it to the tea leaves.

>>2878

>I need help with step #4

Mount your water tank directly above your cup bay and have a valved tube coming directly out of the tank's base. Use your 'the water is hot enough' sensor from 3 to open the valve, and your 'the cup is full' sensor from 5 to close it.

It is the most direct, and simple, solution. unfortunately, if you use hard water, you'll end up with lime scale in your tea or you'll need a filter that will require regular cleaning

Alternatively you could have an external siphon pump leading to a similarly valved tube. If you then also use a floating intake pipe, you can avoid sucking up any lime scale. Basically, you would be copying the flushing mechanism from a toilet and putting it on the outside of your tank. It's a little bit more complicated, but would produce superior tea.

I would also suggest researching tea-making methodology so that your teabot makes a perfect cup every time. You may have to design different settings for different types of tea, though.

Teabot needs to be fully automated, also tipping the container to pour scalding water everywhere is no beuno
>>2897
We are going to mount the hose from the side of the tank and not have our tank suspended over our teacup.

do you mean have a hose that comes in from the top of the tank and floats on the surface so that it takes the top layer of water and not the bottom?

>*When I was doing the design work for an automated vacuum cleaner, I found that it was better to use the most complicated and technologically advance systems available to do the job. People just aren't impressed by simple and efficient devices. They want LAZORS and radar and environment mapping.

Judging from the roombas I have seen they went with your simple designs and not the lasers. The automated robots out not just bump into everything and use that to map their environment, the only other sensors they have is 2 infrared detectors for cliffs and little lighthouses you can set up to prevent them from coming into a room.

OP, this sounds like an elaborate Teasmade(R)

>do you mean have a hose that comes in from the top of the tank and floats on the surface so that it takes the top layer of water and not the bottom?

Yeah. I'm not sure why, but that's the first solution I always think of even though it's not the best. What you want (to keep the lime scale out of your tea) is something like <-- pic related.

>We are going to mount the hose from the side of the tank and not have our tank suspended over our teacup.

If your water level isn't above the highest point that you will fill the cups to, you will have to pump your water from the tank to the cup. A siphon just won't cut it. You could mount it higher than the cup, but not directly over it.

if the water isn't high than the cup, you will have to pump it, and that requires additional stuff: It's not good if you want to stick to the lego parts.
Putting it in a higher position and linking it with a tube to the top of the cup, and put a valve there, is the best solution imho.

Move to China, Engineers are respected like doctors there.

i feel bad for y'alls right side of ya brain

>>2835 is actually write, interestingly enough.

Specifically though, I've found that focusing on the problems is the important thing. It gives you a goal to accomplish, so that when you are reading through the textbook you are actively trying to find the information you need so that you can solve the problems.

After that it seems like mostly a matter of practice makes perfect. In the same way I practice a song on the guitar until I can literally play it with my eyes closed due to muscle memory, I think that doing science courses goes the same way. Eventually you see a problem so often and solve it in the same general way that your brain just sort of automatically recognizes what to do, and the more you practice the quicker you get.

>>2889

>is actually RIGHT

Fuck.

modafinil.

I just do all the exercices that the teachers tell us to do (they're not checked in my school), and before the exams I build up enough tension to study for hours all day without deconcentrating.

first off that diagram is wrong
The amature magnetic field should be in the other direction LRN2righthandrule whoeve made that
anyways both of my parents worked for defense. My father worked for Naval Research Laboratories (NRL) and my mother worked for MITRE (which is not an acronym)
They both could tell people what they did and sometimes the general idea of the project they were working on. What they couldn't tell was specifics, which is understandable. If my father wanted to do work at home he needed to use a computer which was sanctioned (and issued) by NRL as a matter of security.

The commercial sector is still going to be anal about their secrets sometimes more, depending on who you work for. I guarantee google or norton would be super anal about their source code.

you don't need to work in the military to get a civilian defense job, although being a soldier always looks good on your resume.

There are tons of jobs that aren't in the DoD but in their contractors. Oracle, Boeing, Lockheed Martin, Northop Gruman... the list is near endless and they all have need for an EE.

Sounds pretty normal for huge business with R&D. That's how it works in the R&D lab where I work, which has very little to do with military stuff

title: howstuffworks.com fucks up again.

srsly these guys are why your teachers care about your sources. They get shit wrong ALL THE TIME and don't give two shits about it.

I just googled 'rail gun' and copied the first thing I saw, mah bad. Damn image requirements.

>>2901
Well that's good to know. I supposed I'd have to weigh individual companies to get a sense of how it compares to the commercial industries.

>>2905 not your fault there is also a "no file" option in case you didn't know.

https://en.wikipedia.org/wiki/Pulley

>>2882
Didn't help.

imagine the pulley in the center is fixed (ignore the rest to the left for a moment) and the upper right rope being bent downwards around another pulley. you´d have to add another weight of the same mass (m) as the two others to keep the system balanced. so in fact there´s a force of 2m pulling in the pulley in the center, even if you remove the added pulley (and weight) and remount the rope to the wall.

this is the end of my wisdom and i start wondering if there is any difference after all to a configuration with only one pulley and a rope hanging down on both sides, one end with a weight of m, the other with a weight of 2m.

what would the upward acceleration be in this case?

>>2885

>i start wondering if there is any difference after all to a configuration with only one pulley and a rope hanging down on both sides, one end with a weight of m, the other with a weight of 2m.

The acceleration would be a=(2m-m)g/(2m+m)=g/3, not g/5.
So there's a difference.

OK, a friend of mine explained it easily.
The acceleration of the right mass is twice as big as the acceleration of the left mass; opposite directions.

> 2a1=-a2

Why? If the right mass moves h distance downwards, the middle pulley won't move h to the right, but h/2, since there's rope above and below the middle pulley. Consequently, the left rope moves h/2 to the right and the left mass moves h/2 upwards.

So the speed and acceleration of the right mass are twice as big as the speed and acceleration of the left mass.

Newton's 2nd law:

> F=ma

For left mass we have:

> T1-mg=ma1, => T1=m(g+a1)

For right mass we have:

> T2-mg=m(-2a1), => T2=m(g-2a1)

Please excuse the typos, I'm typing this all out on my phone with a fucked up screen.

Anyways, yeah. I'm just looking for some information regarding the operation of these wells. A Google search yielded results talking about sabotaged rigs, but none detailing how (for safety reasons, I s'pose)

Am I the only one thinking this thread is sketchy as fuck?

>Hey guys, I'm writing a short story about a couple of guys who crash a plane into the WTC, anyone have any info on how this could be done irl? *wink*

Short story, riiiiiiggghhhhttttt...

>>2839
telling him how to sabotage a type of oil well thats use was probably discontinued 40 years agoisn't going to do any harm, you seem to have missed the part where he said "from the 1950's"

I don't know how I would cause one to catch on fire, but oil wells are basically big pumps. I would the oil is held in a pressurized tank. If you make a small enough incision, the oil should disperse in small droplets(somewhat like an atomizer), which could be combustible. However, doesn't crude oil have too many impurities to be able to ignite regularly?

>>2857

> oil wells are basically big pumps

yep, i guess the times when you had to drill a hole and the oil spilled out are over... most of it got blown into the atmosphere. in the meantime pumps are gettig replaced by excavators (->oil/tar sand exploitation).

and still there are people who doubt that this might have an effect to our ecosystem, lol

It's really hard to say whether you're fit for engineering or not, and it's only a choice you can make.

Do you like designing things? Improving things? Increasing the technical and cost efficiency of just about everything?
Imagine spending four years studying all the time, and doing everything you can to understand your material, then imagine that the things you design may very well hold the safety of other's lives in its grasp (because it very well might).

Engineering has all sorts of mental and lifestyle hurdles for a reason, the ideal engineer is smart, creative, well organized, productive/persistent , and friendly (the curriculum doesn't stress the last).

Your gender/orientation probably won't cost you, but as I'm still in school maybe an employed engineer can answer that. I would think that companies hire engineers based solely on merit and personality.

As far as smoking, expect to dial it back some. I smoke and lately I've found that I've had to cut it back in order to grasp some of the concepts correctly and more importantly, focus on the homework associated with it.
It's fine to use it as a stress reliever but only do so when you can actually afford to do so.
For example, all homework done, or a good portion of what you can actually accomplish done? Sure, go ahead and toke it up. I only smoke when I know I cannot be productive with my coursework in anyway.

OP here

I definitely think I will fit into the social and academic aspect of it. I love designing things, and I have a background as a bicycle mechanic. I relate all of my lessons and homework back to bikes, as a means of better grasping the topic, and to further my understanding of bikes. I want to make and design high end componentry.
I can always get my hands-on fix working as a wrench in my bike shop.

>>2860

There are some mechanical engineers that work in fabrication shops. Not many do, but there are firms out there for sure that need a lot of small scale solutions and someone to design and manufacture it. I had a friend who worked for a craning and rigging company that constantly had him designing custom rigs that they would fabricate in their own shop

>Begin building

Get a civil engineer

haha stick to your drawings OP, actual construction of a structure takes a special breed of person.

engineers make more money, and you showed us why[%]

They're not going to teach you to swing a hammer. Stuff like scaffolding and framing is up to the contractor. Go to trade school or work for one to learn that (not much to learn)

You're only going to learn about scheduling, cost estimating and control, and some light business and economics classes.

>>2841
a special breed?
