Engineering

I'm currently a junior in Wisconsin. I'm fascinated by the field of biotechnology and all the possible benefits that it could bring. I'm trying to plan an education path for a career in biotechnology and creating my own biotech company(years down the road). If someone could list the top ten colleges or something or maybe map out what they've done to get into the field it would be greatly appreciated. EDIT: Oh I'm a junior in high school.

I am trying to learn how to design circuits and was going to start with something that is "useful" and design a voltage amplifier. Was wondering if anyone could tell me the flaws (if any) that are in the below problem. The data sheet for the transistor is here : http://www.ortodoxism.ro/datasheets/microsemi/2n3634.pdf and here is my little circuit : Vcc = 10v Ic = 10mA Hfe = 100 Q1 = 2N3635 Ib = (Ic/Hfe) = (.01/100) = 0.0001 or .1mA R1 = (.5Vcc)/Ic = (5v/.01) = 500 R2 = 1/(Ic+Ib) = 1/(.01+.0001) = ~99 R4 = (Vr2+Vb-e)/(9*Ib) = 6v/.9mA = 6666 Vr3 = 10-6 = 4v; R3 = 4v/(Ir4+Ib) = 4v/1mA = 4000 R1 = 500 R2 = 100 R3 = 4k R4 = 6.5k o Vcc | …

I'm looking into a career in aerospace/aeronautical engineering. I've found a lot about the career but the one thing that I haven't found that I want to see are blueprints. Does anyone have an example of blueprints that might be drawn up but the as/an engineers? Or a link to some blueprints? Thanks.

I didn't come up with the name, science olympiad did. Anyways, I have joined my schools science olympiad team, and I have chosen the task of creating a model aircraft to fly for over 2 minutes minumum. I'm sure some of you have been in science olympiad before and have even participated in this event, so, I thought this would be an ideal time to pass this design I came across onto you. The rules are located here; http://www.tx.ncsu.edu/science_olympiad/Tournament_information/Event_rules_nc/wright_stuff_b_06.htm And the design I want to emulate looks similar to this; And this is the one that most people tend to build; The only things we are allow…

If zero point energy is possible (wich there is evidence to assume so, it would just be difficult to cultivate this technology to a useable state) then what would be the waste? (I forgot what the name of the law is, but energy can only be transformed and not destroyed or extracted from "thin air") So, theoretically there should be a waste from zero point energy. What would it be (or what is it?)? A friend and I were discussing this subject and the paradoxes of the theory of realativity and such. We are wierd like that, but anyway (sorry). What do you think/know the waste product is? Because it has to have a waste product according to the law of (whatever it's called, lol)…

I figure that wiring and basic electrical engineering are quite useful skills. I am also interested in the physics involved.But a big problem with talking about capacitance or current or whatever in a classroom is that it is not hands on, and so doesn't help me a lot in real life. So in this thread I would ask for people to suggest very simple projects to give me some experience with basic cicuits, wiring things, stuff like that. Basic is the key word here. While I know a fair amount of basic theory I've never wired a single thing in my life. So a project doesn't have to be big, or educational, or anything. Basically as long as I can make something, and then some…

can anyone tell me how monopolar and bipolar Electrolysers work?

Anybody aware of any good (hands-on) engineering competitions out there for midwestern US high school students?

r u a biomedical engineer? if so, i'll appreciate if u state what u r currently working on n how do u find this field. Also, what engineering program did u enter in university to begin with? n wat advice do u hav for some one who wants to be a biomedical engineer? Thanx <3

Well, coincidentally, while I am making my mousetrap catapult, my drafting class is assigning us a mousetrap CAR fun assignment, wanting us to design a car powered on a mousetrap that would go the furthest. So, what kind of things do I need to note for a long distance mousetrap car? It can be slow to a crawl, but really long distance traveller.

Right im determined to figure this one out ! i have been thinking about it and i no longer would use a bendy metal like i was discussing in the other topic. Now i need to use the same sort of design as they use on thoise bendy lamps. Im wondering if anyone knows how exactly you make one which can take quite and bif of weight around 10KG and what materials to use ! ? Thanks

I was wondering if anyone knows how to go about making a very short-range transmitter/receiver for electronic signals, particularly music. The size of the transmitter wouldn't have to be that big, but the receiver would be preferably small enough to hook to a ear bud. I was thinking of cutting a headphone cable, and attaching an antenna to the jack, with a pair of receivers on each bud. Would this work, and if it is possible, how? -Anjruu

I have a dc motor and it is 800 hp. The problem is that it is pin firing under the brushes when i put it under load. We have turned the the comm,bought new brush holder & springs, also bought new brushes in thinking that they could have been of poor quality. We have also installed shimms under the poles pieces. After checking them the shims were the wrong thickness and not in the right order meaning alum, steel. Also notieced that 2 of the insulators were cracked and replaced. The neurtral was also adjusted. any ideas? It seems to be arcing on the trailing edge of the brush 1) I am thinkin of returning the comm 2) Removing shimms poles may be too strong …

"Impervium? Eternium? What do you call a nearly unbreakable metal? Dr. Richard Waterstrat has been pondering that question ever since he invented an alloy that is nearly impervious to wear. Several years ago at the National Institute for Standards and Technology, Dr. Waterstrat was developing a metal for use in artificial hips and knees. Because the alloy would be implanted into the human body, it needed to be both nontoxic and crack-resistant. He made one alloy by mixing three metals- zirconium, palladium, and ruthenium. The alloy seemed promising, so Dr. Waterstrat sent it down to the machine shop to prepare a sample for testing. Soon after, Dr. Waterstr…

hey i'm making a hexapod robot using nitinol for movement. i've got 50 um HT flexinol wire, and i put em on each joint on both sides of it, so it works kinda like how real muscles work, contracting in opposites. i kno its nto the most efficient but w/e, this way allows for better stability than a rigid system. i'm trying to get it to move super fast, thus the thin nitinol, but with great stability (cockroaches) i'm really new into this whole area, i just have to do it for a skool project, but i'm already stuck lol i cant get my nitinol to contract, even with just a simple circuit, i have 1 double A battery holder, attached to a 4.7ohm resistor n' when i touch the ends t…

Hey everyone. I need a bit of help with the design for my art project. We're working with sculptures of human figures and part of mine is going to be veins. To do the veins I could pretty easily get clear tubing and fill it with red and blue liquids. But to make it even better, I wanted to be able to turn the lights off and halve the only light be that which is running through the veins, almost like fiberoptics. Fiberoptics only release the light at the end though. I want something that you can see light the whole way (so they look like veins obviously). Are there any tricks here to get the light to travel through the veins further? How far do you think I could get it to …

I have recently become interesting in cryogenics and uses. Does anyone do anything in this field or know about it. I just wanted to hear what people would do/have done or know about it. Are there are good books on the sugject btw?

My friend and I are doing a physics project where we need to design and build a car that will travel the maximum distance powered by a party balloon, as in by the force applied by the air coming out from the hole. The maximum weight is one kilogram. The problem is, we cannot decide to minimize or maximize weight. I think there are good arguments for both sides. For the less weight, the force of the balloon has more effect when the balloon still has air inside of it, when it is still applying force, but after it runs out of air, it quickly slows down because of lack of momentum. With greater mass, it is the opposite. We were wondering which would be the best course to …

Hey all, this is about the only science forum I was able to find - after reading some of the posts I determined this is a good source for help and sarcasm if I do something stupid I have a tl1000r (motorcycle) that I want to convert the two exhaust mufflers to undertail sound absorption rather than trying to cancel it out. (There are no aftermarket exhaust systems for this conversion.) I will draw up the design when I get home, this is my first post and wanted to introduce myself. My idea was to perforate sheetmetal and use about 1/4" thick sheet of some decent inexpensive sound absorbing material (obviously with a high heat tolerance because the headers and exhaust …

Dear all, Before I say anything, I would like to say that my understanding in 3 phase electrical power is superficial and that I would be using layman terms to explain my predicament. I hope all of you still can understand me. I discovered that the power supply to my rented shop in Singapore is of 3 phase power. I also discovered that the electrical wiring is wired such that each of my power point becomes a single phase power point. As such, I would like to ask, if it would work if I manually attach wires, such that I could have single phase powerpoints and a three phase power point, working at the same time, running concurrently. (I've got some 3 phase equip…

We're making a "car" that's to run for a racing competition. The track consists of plenty of obstructions like 5mm steel rods for speedbreakers, sand pits, gravel beds, S-bends, 50 degree inclines etc etc... The thing is that it cannot be wireless, and must have wires. This makes it simple for us in sense that all we need to do is strap 4 motors and then connect the left side motors in a group and the right side motors in another group to a 2 way switch each. Here's where I need help: 1. We've thought of putting the motors in a T-joint of pipe and then connect both of them. Will this be good enough. 2. The motors we are using are 12V motors@300 R.P.M, but on…

Does anyone know what is good in simulation software? I'm looking for something that will model electrical, mechanical and hydraulic systems.

Does anybody know where to get pictures of the inside of the zion nuclear power plant? If not, then can anybody show me the inside of a power plant that's similar to zion nuclear power plant?

Here is a question that I decided to post in the engineering section, since engineering is an apotheosis of innovation. I was just curious as to see what kinds of brilliant innovations this would spawn. I'll enter my answer to the problem on January 31st, however, I doubt my answer will be as good as some. Suppose you were put into a room with no windows, and no visible doors. At the center of the room was a light fixture. Your watch, your cell phone, everything that told time, was removed. All you had was your clothes, a pen, a pencil with eraser, a paperclip, and several different coins. Your objective is to build a device which can tell you the time, or time p…
