I got the same score :(

62% :(

LK! We are waiting!

Well, apparently I got every pulley question wrong and nearly all the electrical shit wrong. %60

i couldn't remember half this shit. 73%

Holy crap, I got a 74%, and was pretty sure of most of my answers. I find this remarkable because I've never studied any of it and couldn't articulate any of the reasoning I used. Man, me and mechanics are like this: ||

I feel ripped off and contest question #26 and #48.

26, do they figure that electricity fucking skips the 3rd bulb.
48, SUCK/SQUEEZE/BANG/BLOW, every dude who has ever taken shop class fucking knows this, the explosion of the aspirated gas/fuel mixture drives the piston down and sucks in air thru the valve.

[napoleondynamite]GOSH!![/napoleondynamite]

Also, FINGERGUNS

#26 -- Guessing that it skips the second (middle) bulb as some kind of previously-unknown 'electricity wants to conserve itself' law whereby electrons route around load if possible.

#48 -- If you're right, then I got that one right.

There were a couple that I got wrong because I was being dumb and not smart, so I'm going to go ahead and hand myself an honorary 86. Thanks, vasudeva.

Thank God it doesn't take some pulley/electrical knowledge to run Adobe software.

90%

26. V=IR, in their 'perfect world' the wire has no resistance so there is no voltage across the middle bulb hence no current being pushed though.

48. The piston does move down and create lower pressure inside, but 'suction' doesn't cause the air to move in. The higher atmospheric pressure outside pushes the air in.

Huh. I'll get the LBP to explain it to me. She's a wizard. I only knew any of the electrical shit from looking over her shoulder when she's studying.

The pulley shit was goofy, but it seems to break down so: divide load by number of pulleys involved (and used properly).

250kg/1 = 250
250kg/5 = 50kg

This has just enough old-world 'grampa's machine shop' feel to it that I think I'm right and amn't bothering to look it up even though it could save my life one day if I wake up on Planet Gor.

BALLS

100% I lie-76%, no wonder I'm unemployable,goes off to shoot self in foot to collect the American Dream!

66%

The gears and pulleys I got all correct. But I went to shit on the electrical.

79% for me. I fail by a narrow margin.

Can someone please score lower than me?

90% -got caught up with the pulley reductions and suck or push question.

84% - I have a master's in mechanical engineering, and I work with electricity and electronics alot. So either:
A- I'm and idiot of an engineer, or
B- EVERYBODY HERE IS REALLY SMART!!!!

26. The bulb has about 80x the resistance of the bare wires, so about 1/80th of the current (voltage is equavalent across both sides) goes through the bulb, which is not enough to light it.

santeria: 26. The bulb has about 80x the resistance of the bare wires, so about 1/80th of the current (voltage is equavalent across both sides) goes through the bulb, which is not enough to light it.

Exactly! (?)
I hereby score 100%.

You ALL suck at this.

70%.

I failed and they are sending a guy over to my house tomorrow to smack me around a bit..

^ seriously, pack your shit. You're going for the long walk. Sorry dude.

90% or 450 points.

This hurts a little because I am a mechanic by trade and should have got them all right.

Beating a dead horsie

26) The bulb's resistance is never specified.

And #48 never specifies whether the force of the piston is greater than atmospheric pressure, not to mention the air resistance thru the valve.

350. I did not pass.

My main problem was in the electrical stuff, I think.

Ron Paul believes in a world without electrical stuff. (It's not in the Constitution, so this position originates with and is reminiscent of our Founding Fathers.)

that is an exciting new way to look at the problem... Ron Paul does, however believe in Pulleys. Pulleys are a friend of the constitution.

80%

I soooo suck at pulleys.

98%

I failed to divide (50psi x 14) by the 2psi to get 350psi.

Also, you all should know that I am enjoying a little mechanical aptitude superiority dance at your expence. I realize that this doesn't change one bit the notion that I'm fully retarded, but then again, this retard remembered that electricity always takes the path of least resistance, pV = k, and the opposite of big gears making little gears go fast, is liitle gears making big gears go slow.

OMG.....I passed! I got 400! Will wonders never cease....guess I learned sometning in collegfe after all besides how to drink, play spades and ski!
