Mechanical Aptitude Test

[QUOTE=mcandmar;265102]I can sort of understand the logic, its the lower pressure in the cyl that draws the air in,

this is my understanding of it. when the piston moves down you have a increasing volume which causes the pressure drop, atmospheric pressure is then grater than that in the cylinder, and as the cylinder is open to the atmosphere by the inlet valve the air is then pushed in.

Ask an aerodynamicist and they'll tell you that "suck" doesn't exist.

tell these aerodynamicists they're missing out in life..

OK, got 94%, no google or revision That centrifugal device threw me off, and i made a couple of schoolboy errors on the electronics

Correct...

88% for me - the electronics is easy - its that worm gear and those damn pulleys that got me - kinda hard to visualise in my noggin.

Wow - scored 76% - I know that means I failed...but hey it's better than i thought.. but I still WON'T be doing any major engine work on my S2 myself.
