How many of these batteries http://www.trojan-battery.com/Products/ProductSpec.aspx?Name=J185H would it take to run this electric motor http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270010898261 for four hours?

I'm trying to determine if the electric motor could fit in a pick up truck and fill the truck bed with batteries.

I'm writing a handbook for inventors, and I'd like to know what's most useful in constructing a broad range of rough prototypes? I know duct tape is pretty universal, but I'm not sure about the rest.

If you can answer that question, then I'd also like to know if there's anything special that's essential to building demonstration or working prototypes.

Thanks!

We build littlecomputers (for our own use, but we put them on other people's premises) out of rackmount boxes, mini-ITX boards, some peripherals and a little bit of box adaptation and customising cables.

I'm sure these qualify for self-certification, but I have no idea how we actually DO it for this type of product.

Can you advise?

I've been hearing a lot of conspiracy theories on this matter lately, and I was just wondering what some scientists/structural engineers thought about it. Ive heard some say that the heat of the airplane crash would not be hot enough to melt the steel beams, and also that it looked like there were placed explosives.

Ok, if the jet fuel caused the towers to collapse, which I do not believe, what then brought down WTC7 in your opinion? This wasn't hit by any jet there was no jet fuel in the building, so what caused every support colume to give way at the exact same time for it to collapse onto it's own footprint?

It might have had slight damage to one side but this would not cause every support colume to fail at the same time.

the slope height, inclined at an angle θ to the ground, to half the length of the side of the square base, equivalent to the secant of the angle θ. The above two lengths were about 186.4 and 115.2 meters respectively.
What is the ratio?
HEy its real!
And after i pick B.A
youll see how easy yet hard it is to come up with!

In helicopters, torque balancing is done by the extra rear propeller. But in airplanes, no such balancing is evident. Even the engines of jumbo jets turn all in the same sense. For stability, the Sum of all torques MUST be 0. Is the sum of the propellers or jets torques so small as not to influence equilibrium? If not, what is the mechanism used to stabilize the plane? It seems to me that, except for helicopters, all propellers are small BUT they turn very fast. So, the momentum generated must be quite large. Please feel free to use engineering notation in your answer. Thanx!
