w000!

thats a god point... lol... its centripetal force!

78% , realised a couple of times, as soon as i clicked the next button, i had pressed the wrong option

 

82%

 

86%

 

84 gay percent, im just happy i beat radders

 

I got 310pts 62% lol

 

88%, got the pendulums wrong, the gears that go in reverse/direct/reduce which does seem a grey question as per chip said. Pressure outside baloon which I wasnt sure about anyway. And water in pipe but that was from rushing. Not a bad test

 

I got linked to this via another site in the week. I scored 80% and made a couple of silly errors realised after Not bad seeing as I hate doing electronics.

*Edit: I chose suction too

 

88%
im with the suction thing,not atmo

 

could suction not be a viable anwser caues if you put your finger on a bike pump and pull handle out it will creat suction wont it same idea ?

 

no, the pump lowers the pressure on the pump side of your finger, causing your finger to be pressed onto the pump by the now higher atmospheric presssure. When you remove your finger, the high atmospheric pressure pushes the air into the pump chamber to equalise the pressure

 

i got bored going through it

 

92%

 

so did i mate,not enough tits.

 

There is no such thing as suction in physics....Its creating a lower pressure in the chamber which is then filled by atmospheric pressure.... the laws of physics mean that any pressure differential will try to even itself out...how much it can even itself out before the valve closes has an effect on the VE of your engine.

try telling my missus that,suction like a dyson on 3 phase.

 

80%

 

84%... first time i've done a test like that since i left college! mis-read one and did a few wrong clicks, so probably 90%ish in reality

 

the suction thing is odd though, i'd say the piston travelling down causes a depression in the cylinder which atmospheric pressure tries to fill

 

There may not be such thing as suction in physics but there is such thing as vacuum. the two arguement are saying the same thing just in different ways. Both are correct in my opinion

 

Also doesn't an engine work like this... SUCK squeeze bang blow?

 

it doesnt really suck, it doesnt really BANG, it does squeeze, and it doesnt really blow

a vacuum is relative, its just a pressure lower than atmospherics pressure

 

the "suck" is caused by the difference in pressure
it does "squeeze" but it doesn't "bang" otherwise your engine would be all over the shop
it's called a controled explosion
and it doesn't "blow" but it's the reverse of the "suck"

see "suck"

 

370 74% here.

on at least 3 of them i didn't read the question properly (my fatal error in my school exams too!) and only afterwards realised what a gimp i'd been.

 

44%

 

82% and 410 pints - i passed

 

Snap!

320 points out of 400, 64% You failed

Wasnt going to say anything but fuckit

 

...oh how many answers were lies on here

...and i got bored at question 4..way too hard

 

good quiz thatm shouldve read some of the questions a bit more thoroughly tho only managed 82%

 

300 points 60%, a lot of years since I was at school, wasn't very good at physics and don't have any mechanical knowledge at all, I wasn't too bad at the circuit questions though, the rest just tried to work out with common sense, my brain switches off when I find something too hard

I only went through all 50 as I thought it would give you a summary of what you answered rightly and wrongly

340 68%

 

64% .............. i dont claim to have a lot of knowledge on the subject, but more importantly........ i was beaten by a girl

 

90%
I'm pleased

 

I just re-did it (was thinking about gears 'n stuff on my walk to town!) and got 70% 350
be interesting to see what ones were right, I can't do the loads one, I am sure there are ones that should be obvious that I've got wrong

Z

 

nice just off to try this

 

You can review the test pal, before you exit, there is a magnifying glass symbol at the top, and if you click on the panel at the bottom of the page you can review your progress as the test goes on....

 

Bollocks I'll have to do it again now

 

90%, and im suppose to be an engineer , however I have just done it whilst eating my tea and not concentrating to much!
