This is a pop quiz...have you studied?

I suck, I did not pass :thumbsdown:

Back to the books for me 68%

 

[JulesMaximus]

50 questions? Holy crap!!! I don't have time to take this test...although the first 5 questions were easy.

 

[Scouzer]

74%...and I can hardly change an air filter

Most of that stuff was Grade 10 or 11 science...the pulley and cog questions were Grade 8-9 stuff which made it harder to remember

 

[thirdeye]

Ouch I got a 66%

I sucked at the weighted pulley questions. Got them all wrong.

Me too and I don't know circuits because I never took physics.

The pulley ones with the weights, I had no clue.

 

[jagec]

80% is a passing grade? Holy crap.

I feel guilty about my 94...I should have slowed down and gotten a 100.

Most of it's pretty intuitive on reflection.

 

[Eos]

Oof.

50%

exactly what i was thinking... i started to do it then realized after about 7 or 8 that there was 50 total

 

[Demon-Xanth]

I got 92%, though one of them was the difference between laymen's terms and what your science teacher told you.

Are you kidding? Those circuits were Grade 9 Science for me...

 

[yelo333]

440 points/88%

 

[imported_Truenofan]

86%, and I'm tired too...damn electrical section.....i guessed on some of em, at least i learned something on the electrical circuits that are plotted in a manual.

 

[exdeath]

92% here. Missed 4

I missed two of the complex pulley ones because I went through them too fast and didn't zoom in and missed some pulleys that were fixed or moving (generally you divide the force and distance of the load by the number of passes of cable supporting the load, but multiply the input work). Pulleys work because you have the energy capacity to apply a smaller force for a longer time and distance, but not a large force all at once.

Missed the fan one, I put opposite. But thats really a trick question. Though they would rotate together as if sharing a shaft as shown in the picture, individually they have to be opposite CC and CCW shaft rotation with respect to their own housings for that to happen.

And the balloon one I missed because I thought it was a trick question, the atmospheric pressure is the same everywhere, but then I reread the question and saw that the gas in each balloon was the same amount, thus the smaller one has a higher external pressure.

 

[overst33r]

80% Those pulleys straight kilt me...

 

[kami333]

82%

 

[LordMorpheus]

96%. The two I missed I knew as soon as I clicked. For some reason I was reading the electrical symbol for the battery as a resistor. Oops.

I guess I should have the mechanical aptitude - I'm a senior mechanical engineering student.

 

[Vic]

86% but I flew through it in like 5 minutes.

Hmm... reviewing it, it looks like I made a couple of stupid mistakes caused by going too fast (most transposed answers), but I disagree with #48. If air enters the cylinder due to atmospheric pressure pushing it in (rather than suction from the piston going down on the intake stroke) then how do they explain intake manifold vacuum?

 

[996GT2]

92%...not bad IMO for a senior in HS who's planning to study bio/chem instead of physics

Ditto.

3 wrong, 2 of which I hit "Submit" and immediately went "oops", the third being due to an inexcusable sudden failure to remember which was was "clockwise".

That's a technicality. I missed that one too and as soon as I hit Submit I knew I was "wrong". There's technically no such force as "suction". The "vacuum" is a low-pressure area and the air enters not because of suction from the vacuum, but because of pressure from outside the vacuum.

Ah I see. Trick question. My bad.

 

[Fenixgoon]

76% and some of those questions were poorly written/drawn

 

[Tiamat]

plenty of mistakes in the questions... PSI is units of pressure not force for example... Kg is units of mass not force... still taking the exam...

exactly. 86%, 5 minutes for me too.

90%, I got tricked by the vacuum one too and I made a couple other click happy mistakes that I saw right after I hit next. O-well.
