Outer Limits 4x4 Board

You engineers and mechanics out there better get 100% on this test.

Lucky I can't tell you my score yet, as I'm only just a few questions into the test so far.

Q31 is fucked! The diagram is poorly drawn. If it was accurate, the correct answer isn't there.

Is that the one with lots of pulleys?

I agree there are a few shit questions like that - can't remember which ones now. Pretty dodgy test - if i were marked on that at uni there'd be trouble

...none the less i got 88%

-Stu

shit questions i remember:
one with lots of pulleys
oil/water one

92%

Two masses on an uneven balance.

I farked question 44. I knew it as I was on the next question, but couldn't go back.

The question about the n/a engine cylinder is a little crappy too - I'd accept either of two answers, but I reckon I know which one they want.

Why is the oil/water one shit?? oil has a lighter SG than water, so it floats

Yeah probably right.

The offset lever one was a bit dodge too wasn't it?

Not being able to go back sucks, I know where I stuffed up and realised after submitting, What score ??

98%

92% as well

440 points - 88% But I could do better next time

i got 74%... stuffed up the parallel voltage one... and the engine one is crap too... and the uneven balance with two equal masses.

Several of my mates are engineers.. i shall see what they get

I can think of at least three OL'ers I would expect to score 100% - but I won't name names.

12 %

haha nah I'll do it when I got some spare time

88%. Not perfect, but not a dud.

74%. I expected lower. It stuffed up at the end so i had to calculate my own score. 13 wrong out of 50.

Agh dammit, I got Q31 wrong. Agreed, it's a silly question. Should give dimensions or have only one remotely reasonable answer.
I agree with scott on the cylilnder question. Knew which one they were after

If so it'll depend on the map on the CPU as it depends on what map you use as to what the rpm will be.

an example
a bad map might be 3000rpm for 100klm chew up heaps of fuel.

A good map might be 1500rpm for 100klm and use very little fuel.

Gearing won't mean much if the engine has EFI.

can anyone troubleshoot this guy's efi though?

Steve.

I got 88%. Bit disapointed usually do better on mechanical reason tests. But oh well. Still not bad.

goit 80%, although i swear going back through them that the answer i clicked and the answer it said i clicked were completely different.

and the engine one... isn't the air drawn into the cylinder due to a difference in atmospheric pressure vs that of the cylinder? and what causes the difference (yes i got it wrong)

78%... not to bad seeing as i have no mechanical background whatsoever well methinks so anyway!

88

Those pulleys and the piston kill me ..

were's my prize, I got 100%

You get to be an apprentice mechanic!

90%, not bad for someone who sorts mail all night. That must be why I am heading out soon to drive trains.

You can review your answers. Agree the engine one is a tad BS, if the piston wasnt going down, there would be no room for the atmosphere to force air in, so it really is the piston suction doing it, creating a vacumn.

What was wrong with how it was drawn? And what would the correct answer be?

96%...got 38 and 47 wrong....not bad for an it nerd...

No, its pushed in by atmospheric pressure, Naturally aspirated

96%

Q8 - Sun gear - wording is very poor - rotates vs turns (I got confused)

Pulley questions - should say to neglect pulley friction

Q44 - Venturi - I don't beleive their answer. My spa bath shows very clearly water doesn't rise up the venturi tube. (second tube). First tube would rise due to static pressure before restriction.

But I am only an IT geek.
