Yeah, didn't do physics at school & dont' know jack about electrical components - 72% - looks like it's my shout.

The one with the multiple stacked variable diameter pulleys had me thinking for a while...

I also was a bit confused as to why the elec symbols were included as that is not a 'aptitude' test, its a knowledge test...

Oh yeah, the water flow and a/b tubes - I was going to call it for being a venturi and say A only, but then based the decision I made on the arrow going in, so called A biggest and B smallest. I probably shouldn't have gotten 100 for a couple of lucky guesstimates!

shame, 74%.

number 48, 'from suction caused by the piston going down' and 'atmospheric pressure pushing it into the cylinder'. they both are basically the same. It's diffusion: an area of high pressure to an area of low pressure. Vaccuum i.e. sucking it in is caused from an area of low pressure, atmospheric pressure pushes into the engine being an area of high pressure.

RIGGED.

I never did physics either.

P.S. Learnt 'diffusion' from human biology. That's how we breathe.

I think this test proves something about me...

I think I was doing quite well until the 12th question when I glanced upwards and realised there were 50 questions in total I closed the browser cause I simply don't have time.

Same as all my cars.....never get complete cause I start them then run out of time!!

430 for 86% .. and i do this sorta stuff all day (mechatronic eng).

im claiming i wasn't playing attention

hahaha, yea i did that but i kept pushing on (as i was in English writing... zzzzzz) and i think i got,

290 - (forgotten percentage)

c'mon... I'm an english man my self.:rolleyes:

Oh and what was the answer to the last question?
I just took a stab in the dark, as i did with many of the questions and did the bottom shaft hehe

90%

I suspect the test is bs though, as one of my questions didn't even have the correct answer as an option:

Q46
"Rapidly compressing air and raising its pressure will have what effect?"
A - air will cool
B - air will heat up
C - no effect on temperature

First of all, they are saying the same thing twice...

Also, they seem to be forgetting that the amount of heat will not change, as no heat energy is entering the system (you are merely concentrating the heat energy already existing in the air), which means B (and definetly not A) are not correct. The result of the compression of air will be an increase in temperature (but not the amount of heat), which rules out C.

I'm guessing the creator of the test has not done much chemisty, and is not familiar with the ideal gas law: PV=nRT

I think I could be better spending my time on my engineering assignments, and not picking on internet questionairs....

Cheers,

RB

pftt ideal gas law .. find me an ideal gas..

i think the phrase the air will heat up is correct as the pressure is being increase (this takes energy to do this).

HAHA its a Ford website wt u expect :p

i got 78% and in my defence i didnt read the questions properly and rushed thru it. also theres too many about gears lol
