- Q: I am going to be starting college soon and I would like some input to these two engineering majors. I know I want to pick one of these but I dont know which. I love building things but I also love tinkering with computers and technology. I've read that ECE has a better job outlook as well as a better salary. I think I might like ME because of the hands on although i think alot of it is designing on computers.[. I know I have time to decide in college. Any Help/Opinions??
- In terms of jobs, opportunities, money they all are basically equal. The question is what type of problems do you like to solve. I went into Electrical because I aced those chapters in high school physics. Today I solved several problems. I had one phone conference. Help plan a project, work that was to be done, material needed, key people. I made several follow up phone calls to see where key equipment and what calculations were completed. I reviewed a arc flash study, spot checked by hand a few of the computer calculations. Programs a great, but garbage in garbage out. About a month ago I was out in the field, and my friend Chris had a problem. Chris may be a mechanical engineer, but he is a real motor head. Chris is an expert on rebuilding 50 year old electrical equipment like 15kv breakers. This breaker would not open, and it was stuck so you could not unplug it. Chris injected lubricant into the socket, and had the men rotate the coupling by hand so the lubricant (special lubricant that Chris had to specify and buy) would penetrate. The were then able to unplug the breaker for the first time in 30 years. Chris then had to figure out what was wrong with this complex piece of equipment that can interrupt a 25,000 amp fault in 5 milliseconds. It turned out some grommets were worn. Chris replaced the grommets with ones he had specially machined. Chris then had to tune everything up so the breaker could interrupt a 25,000 amp fault in 5 milliseconds. The only other engineers who can do this are old enough to be Chris's dad, or granddad. These are some of the things real engineers do.
- Q: i need what to do in a bad thunderstorm
- definite. The turbulence interior a thunderstorm could nicely be very severe. in certainty, as a thunder cloud (cumulonimbus (cb)) is turning out to be, the air interior is being pushed up and large velocity and carried with it water particules. To fly with the aid of a cb is risky for the reason which you will positively stumble upon severe icing situations. Icing could reason subjects with the engines, besides as with the raise produced via and the soundness of the plane. it could additionally block static and pitot vents (required for various contraptions interior the airplane) whilst a thunderstorm is energetic, the water is in certainty too heavy and starts falling down interior the path of the cloud as hail or rain, yet this additionally reasons downdrafts (severe velocity wind transferring downwards) alongside with the updrafts this creates severe turbulence and in very great thunderstorms the rigidity from the downdrafts must be sufficient to rigidity an plane downwards in the direction of terrain. At airfields, physique of techniques and landings are no longer oftentimes allowed whilst an energetic thunderstorm is interior of sight because of this and likewise the prospect of windshear. With regards lightening - it is not the main deadly part of a thunderstorm in any respect. There are static wicks to disperse the electrical powered energy. in spite of the undeniable fact that, a marvelous flash can quickly degrade a pilots ingenious and prescient which isn't so risk-free. we've climate radar and could see the place they're and stay clear of them yet around the equator, multicell thunderstorms can selection for 100s of miles wherein case the very turbulent centres could be prevented yet patches which teach as lighter factors (amber on the climate radar) ought to nonetheless be flown with the aid of.
- Q: I am in need of some information where I can go to find information in medical literature regarding electrical shock. My precious (a young surgical RN) daughter-in-law experienced a serious electrical shock at work (in an operating room). To this point, I have not talked to her to get more details but she is still very ill from this. She has migraine headaches, abdominal cramps, tingling in her arm etc. I am very worried about her. Some type of equipment malfunctioned it destroyed the equipment severely shocked her. I am not certain of what tests she has had done all, as she is sleeping all the time from the exhaustion too ill to be up much. I just need medical information so I can give her to make sure she gets proper tests such is properly informed as to what all she needs checked out. She has never yet had children wonder if this will affect her eggs?Please help. She is too ill to research this my son is very busy away some.
- If you say the baby is moving, and acting normally as he has been doing in the last few weeks, the chances of something being wrong is pretty slim. Also, like the others have said, please confront the restaurant employees or manager, shocking a normal person can be bad enough. But when you are pregnant at 31 weeks, its almost like planned abortion. Definitely confront them, as it could earn loads of compensation which could help with the baby.
- Q: Do you find batteries die faster than they should, light bulbs flicker or go out too quickly, electrical equipment does werid stuff or dies sooner than it should. (If you don't believe in vampires, this question is not directed at you.)I suspect it's more of a psi-vamp than sang problem, but I'm currious. I've had some weird experiences with the computer and one small printer ar work. Also, I had a period where remote controled TV's would go on by themselves. I don't have that problem now, though.
- Yes I am a psy/sang, I have had many issues with my printer, flickering computer screen, lights, cellphones etc. I think this has to do with us just being higher frequency people? I don't know, but I find it weird.
- Q: I am doing a project on electronic baton.I want it to look exactly like baton used by professional orchestra conductor.I stored the electronic components inside the handle of the baton.The problem is the space is very limited.The maximum diameter of the handle only about 18 mm.I need to choose a battery that also stored inside the handle.I want the battery that could work for long time.However what I can see the coin battery that is small only have small energy in it.It will only last for less than 1 hour.It is not good for new product.What can I do to maximize amount of energy so baton can work for longer time? ideally 10+hours or minimum of 5 hours and can fit inside small handle.I dont want to use external power cable.Hope you guys can help me.Really appreciated all of your helps.
- what i can't believe is that you've found a gyroscope, microcontroller, and bluetooth circuitry to fit in there - please tell us the manufacturer and part numbers for your parts - i would love a microcontroller that small - not to mention bluetooth
- Q: I just moved to a house in Vancouver, WA, and am wondering what companies can ship/move a large storage container (like PODs) from Houston, TX to here in WA. I will be doing it within the next month or two, and need a general estimate on how much it is going to be (I can figure that out, just need some websites or company names)
- PODs, U-Haul has something similar but smaller and ABF freight has a small POD to a you fill the entire trailer.
- Q: I have heard from a lot of people about the greatness of an EE degree but never got the chance to ask why? So what is so cool about an electrical engineering degree that makes it better than the other engineering degrees out there?
- I've got a Electrical Engineering Diploma. I work in the electrical field. I'd be a Graphic Designer.
- Q: direct tv came to the house we just moved into and the power went out when he was hooking up a reciever and turns out all our outlets are messed up except two. one is completely dead. one was red on his tester thing and he said that is dangerous--forgot what he said about it and all the other are open ground i guess, and the fuse keeps blowing. is there any way to fix it without an electrician??? my husband knows some electrical stuff thanks
- Not a big problem first you have to find the short then get the ground wire working start by removing ALL loads on that circuit and pull the outlet covers then start with the wire disconnected at the breaker box using an ohm meter follow it as it was wired separating everything if needed to pin point short then when you got infinite reading hook back the wire and find the broken ground (sounds like a ground was hooked to a hot maybe
- Q: Also, do students studying to become either one of these need to study things like how to program an java and stuff?
- I am studying Mechatronic it's a mix of both. You need C for sure as an electrical engineer.
- Q: I measured it with a CRO in the physics lab and I was wondering what could be its source
- That is a period of about 62 hours or 2.5 days! Are you sure you measured this with an oscilloscope, or does CRO mean something else to you? Maybe the motion of the planets, earth, moon, etc. I don't know? Do you mean a period of 4.5 microseconds? That would be 222kHz perhaps EMI from a computer, other electronic gear, short wave radio, etc. If you can clarify, I might be of more help. Edit: OK; I have a couple of ideas, but it can be DIFFICULT to find. I spent a long time trying to track down the source of 70MHz in my lab. Turns out there is a TV station (channel 4) transmitting about 1 mile away. Channel 4 occupies the space between 67.31MHz and 71.75MHz. 222 KHz has a wavelength of about 1350 meters. It takes a pretty big antenna to launch that as a traveling wave so I'm going guess its a near field source. A good way to look for it is to make a small loop antenna with a few turns of magnet wire (maybe a few 10s of cm in diameter) and hook it to your oscilloscope. Walk around with it putting it near any and all electrical equipment that is in or near your lab. Make sure to change the orientation of the coil when you are moving around. You are basically playing a game of hot and cold. Try to maximize the signal and in theory you should be near the source. Also, be suspicious of the lights. I know their source is 60Hz, but some electronic ballasts for fluorescents run at a pretty high frequency, at least 10's of KHz, you could be seeing a harmonic. Just try flipping the lights on and off looking for a change in amplitude of the signal on the scope. If this doesn't find it, then perhps it is far field? I don't know of any commercial braoadcasts at this frequency though. The low end of AM radio is around 500KHz. Maybe you have an active Ham radio operator in the neighborhood? I wouldn't think he would be transmitting all of the time though is this 'noise' always present? Hope this helps. Let me know if you find it. Dave
