Engineering - February 2007

Last answers wasn't good enough still don't quite know how it works. I'm working with MD-500, 600's, 900's all the F models, the M's, etc.

Gas engine is fairly simple, just like a transmission. But how? do you get the rotors rotate? All I see is a huge intake on top just behine the main rotors, have a fan going threw the back "which is very flippin awsome" and the exhaust flaring to the left. but all I see in the engine compartment is a kinda like transmission looking thing thicker, allyou see in side over the rear jump seat is a circle shaped thing, not very big at all.



Is it rocket science? Or is it just that simple? Big future with helicopters ahead of me, so i'm needing to understand EVERYTHING in this science. Yes I think I might be able to land a Shwietzer*?? 900?? Looks too easy, I'm pretty good at aviation.... flight simulator, longbow game, etc. Dad was in the Airforce..

A charging RC circuit controls the intermittent windshield wipers in a car. The emf is 12.0V. The wipers are triggered when the voltage across the 125(micro)F capacitor reaches 10.0V; then the capacitor is quickly discharged (through a much smaller resistor) and the cycle repeats. What resistance should be used in the charging circuit if the wipers are to operate once every 1.80s?

Say the voltage of the house went from 120volts to 108 volts. What would be the power consumed by a 100 watt bulb (that is, a lightbulb that consumes 100watts when connected to 120volts).

1. What are the specs of the DC motor/other required to/capable of creating a Wind (or other source) Powered Generator that will run a standard home on its own (or 12,000-16,000 kWh per year)

2. What is the torque (in Newton-Metres or Foot-Pounds) required (to be generated by the wind/other) to move that shaft fast enough to generate enough power for that home.

3. What is the speed that that shaft will be spinning (in Hertz/RPM/other) because of that Torque in #2.

Bonus 4. What is the resistance of that motor/other, that is, how much inherent resitance does it have to turning the shaft. (Probably answered when 2 & 3 are answered?)

Anyone who answers all three questions will not only get the 10 points, but I will personally look through your previously answered questions and give you up to 10 thumbs up for any answers I don't hate. Runners up will get a thumbs up, identical correct answers will get the 10 bonus thumbs up as well, all BS answers will get reported. GOOD LUCK!

We frequently use backgrounds from other disciplines and there are layers shown in the Named Filter Layer box that do not show up in the list under Show All Layers.
I delete them now by highlighting the layer to be deleted in the Named Filter Box the selecting delete. That works until the file is closed but when reopened the layers again appear.
Any help would be appreciated

We have a power supply for electrophoresis which I am writing a safety analysis of. The power supply is 120V, 60Hz and the fuse rating is 1A at 250V. If it makes any difference, the supply is plugged into a GFCI outlet. As the gel tanks need to be covered to get a current, electrocution should only be able to happen by touching a live lead connector? What is the most likely result of an accidental electrocution from this apparatus? Thanks a lot.

A homeowner wishes to insulate her attic with fiberglass insulation to
conserve energy. The insulation comes in 40-cm wide rolls that are cut to fit between
the rafters in the attic. If the roof is 6 m from peak to eave and the attic space
is 2 m high at the peak, how long does each of the pieces of insulation need to be?
Round to the nearest tenth.


16. Geometry. For the home described in exercise 15, if the roof is 7 m from peak to
eave and the attic space is 3 m high at the peak, how long does each of the pieces
of insulation need to be? Round to the nearest tenth.

I was thinking recently that the Japanese Really haven't invented anything original in the past 100 years. We invent the computer, microprocessor, television, etc, and they go ahead and make a better contraption. However, they didn't actually invent any of this stuff. And no, Nintendo does not count: It's more of the same.
