Q: If humidity of a spacecraft is too high, how can it affect a crew and its equipment? what if it was too low?my sister did not get to go on her field trip but they gave her the worksheet this is the only question she cant answer please help!: mold can make people very sick or die. also moisture could iodize electrical equipment.

Q: I need definitions of ship EquipmentMain switchboard:Distribution bus bars:Ship service generators:Main Engines:Prime mover:propulsion generators:propulsion motors:: It is assumed that this enquiry is in respect of large cargo or passenger vessels, not little pleasure boats. Main switchboard. This is the electrical switch panel to which all of the supplies from the service generators are led and from which all supplies to engineroom electrical equipment, deck machinery and the ships general electrical equipment, galley, navigation equipment, lighting, ventilation etc are supplied. The main switchboard comprises distribution bus bars, switches, meters and on AC ships, now in the the majority, the equipment required to synchronise the phases of the service generators. The distribution bus bars are the principal electrical conductors to which the generator outputs can be switched and from which the circuits to the rest of the ships electrical equipment are supplied. There are usually four bus bars, three carrying electricity at 415 or 440 volts three phase and a neutral bar. The current is usually supplied with a frequency of 50 Herz or 60 Herz. Ships service generators are in modern ships alternator units which supply all electrical requirements with the exception of the ship's propulsion. They are normally powered by diesel engines or steam turbines and in some naval vessels by gas turbines. Main engines. This term is invariably used for the vessel's propulsion machinery. Prime mover. This is a general term not restricted to marine practice for any machine the converts the energy of a fuel or the heat energy of steam into kinetic energy. Propulsion generators. These can be DC generators or AC alternators which have outputs dedicated for ship's propulsion purposes. The are usually connected independently of the main switchboard via a dedicated propulsion switchboard. Propulsion motors. These are electric motors which drive the ship's propellers. They are usually inboard but many modern cruise ships have their propulsion motors within pods which are outside of the main hull.

Q: I am an undergraduate in Electrical Engineering and I want to design and work with generators. What institutions research electrical generators? What companies design/build electrical generators? What is the difference between electric drive systems and generators? are they the same thing?Much thanks.: Electrical engineers design and research electrical generators. The specialized of use generators attached to primary power (like diesel engines) to produce power to run electric motors for power and speed control, is also electrical engineers but for completely different companies involved in transportation. And I answer this way because of your mention and confusion of generators with electric drive. If you mean electric drive of things like conveyor belts or electric trains/trolleys then that doesn't involve generators at all, only motors. Still electrical engineers.

Q: Every other electrical and electronic equipment in my house is alright. How can alarm company prove the above in a court of law or to Better Business Bureau ?: The alarm company employs the expert who says so! I'd say it is completely possible. One problem with an alarm system is all the wiring connecting it to the various triggering devices. It is usually long, and elevated, not shielded in any way. It works like a large antenna. So, a lightning flash doesn't even have to cause a surge on the power lines, in order to induce a voltage on all this wire. Distant lightning will produce an EMP (electro-magnetic pulse). It is like a strong radio signal. It only has to exceed the breakdown voltage of any chip it can get to. As this has to be some particular chip, it could be taken out alone. It only takes the destruction of a single gate in it to render it useless. I'm sure the manufacturer would have had enough experience to realise the cause of that particular chip being taken out! Nothing else in your house can present such a large antenna to the pulse.

Q: Im doing a report and I've looked jzt about everywhere and i cant find the answer to this question, please help: Exports: vehicles 25.9%, machinery and electrical equipment 21.3%, base metals 14.6%, chemicals and minerals 10.1%, plastics 5.4% (2004) Imports: machinery and transport equipment 41.1%, intermediate manufactured goods 19.3%, fuels 12.3%, chemicals 9.8%, miscellaneous manufactured goods 10.2% (2003)

Q: I was wondering, if everyone on earth was to disappear and there was no one to work the electrical grid, how long would it take for 1] The electrical power lines themselves to decay?2] The electrical substations to break down?3] The transformer units to break down?4] Any other electrical equipment to break [such as those boxes on the power lines, as well as ANY other piece of equipment on the electric grid]?P.S- Don't give how long it would take for the power stations to stop running, I already know that. Just answer the four questions I asked.: Electrical substations may break down. 2]. Substations require regular maintenance.

Q: I am studying in college to become an electrical engineer but there is one problem, i'm almost clueless about what i'll do once i graduate. like at what kind of companies and places will i work at? what will i be doing? whats it like to be an engineer? what will be my dutys?. and also how much does an engineer (more specifically the kind in my field) earn? really need to know this. thanks: I okorder

Q: i.e. extended warranty.: I know this isn't much of an answer but I think it depends on the item. For example, I bought a $32 toy and toys-r-us tried to sell me a warranty that was $12. Doesn't really make sense. But the warranty on my flat screen TV is probably a good value. -- On a side note, it is wonderful that items are so cheap now that we have to consider the value of the warranty but I am worried about out throw-away society. I had a neighbor that just bought a new lawn mower because it leaked oil. That would cost $12 to fix. Oy!

Q: A. Lockout/Tagout involves placing a physical lock and a tag on electrical equipmentB. Lockout/Tagout is necessary prior to working on electrical equipmentC. Lockout/Tagout is intended to ensure that electricity is not returned to the equipment by anyone until it is safe.D. Lockout/Tagout is to be used only in extreme cases of potential electrical hazard.: D is not true - a lock out tage is used whenever applying electricity to the circuit would result in dangerous conditions. When repair work is being done on the circuit equipment for example. Lock out tage are used for more then just electrical too.

Q: If I bring my laptop (North America 60Hz) and use it in Europe (50Hz), would it work properly?If so, does that mean my laptop/power cord has a frequency converter?: my laptop has an internal battery, so it can operate with no outside voltage at all. The power adaptor is rated 100-240 volts 50/60 cycle input with no adjustments needed. such ratings are very common for this type of equipment. what will be needed is converters for the blade type plug to the kind in use for the country you are visiting. If you are going to be in Europe for an extended period, you should be able to get the proper line cord for the power adaptor from the computer manufacterer.
