I got 86%


Anyone beat it?

Shame it doesn't tell you which you got wrong.

 

[grego]

Only 40% lol, it does tell you which you got wrong, you could click on the icon on the left

 

[WillowTheWhisp]

I didn't beat you. Only got 80% and I'm intrigued now which I got wrong too.

 

[Gayle]

I was doing ok but stopped understanding the questions when I got to question 8 - I'm not mechanically minded!

 

[WillowTheWhisp]

I can't help querying the answer to number 8. The correct answer just doesn't seem physically possible to me.

 

[Neil]

I started doing it but when I saw there were 50 questions I decided I could not be bothered. That and having to sort out stuff tonight for school tomorrow with Rhonda being in hospital over night having her lobotomy reversed.

 

[WillowTheWhisp]

So what did you reckon to question 8 Ian?

 

[lancsdave]

I got to about question 5 and couldn't be arsed

I got to about question 5 and couldn't be arsed

I decided not to bother looking

 

[Lilly]

I only got 46% so not very good.

I'm not good at those sort of questions.

 

[John_Timmins]

82% didnt beat you but passed

 

[WillowTheWhisp]

Don't read this if you still want to try the quiz. If you've already done it then please scroll down.




















OK, did anyone get No8 right because I just don't see how those gears could keep turning, surely they would all be stopped if the ring gear is stopped. The cogs are interlocking so once one stops it must stop the one that locks into it.

You're going to ruin your reputation for being nosey

 

[cashman]

got 42% which is 40% more than i expected, owt above donkey broke down,n i'm knackered.

 

[WillowTheWhisp]

I can see I'm not going to get much response to my question from all you mechanically minded lot!

 

[Neil]

Howstuffworks "How Gear Ratios Work"

 

[WillowTheWhisp]

Hmm, thanks Neil, but I still can't find an illustration of a planetary gear system where the inner cog wheels keep turning when the outer one is held still. How can they?

 

[West Ender]

I only got 56%. Don't bring your car to me when it goes wrong.

Shame it doesn't tell you which you got wrong.

I got 94%

It does tell you which you got wrong and it even got one answer wrong itself. Well not so much wrong as having two correct answers and only selecting one of them as correct and of course the other one became incorrect.

Q48 – In a naturally aspirated engine, air enters the cylinder because of

Their answer – From atmospheric pressure pushing it in.

I selected from suction caused by the piston going down, which is the same thing. In fact it is probably more correct than their answer.

The piston moves down and tries to create a vacuum which is equalised by the air pushing in from outside. If the piston didn’t move down there would be nowhere for the air to rush in. The piston doesn’t move down because of the air rushing in but because the crankshaft is still rotating after ignition and pulls it down, thus creating a vacuum, which is equalised by the air rushing in.

So my score should have been 96%.
