Quite interesting if you have a few minutes. There are some real ambigious questions in it mind you, clearly open to debate in many cases.

I got 76%, but that was with accidentially clicking the wrong answer to two questions where I actually knew the right one.

Knowing the level of mechanical knowledge around here, I suspect most will do a lot better!

FORD!!

Shows what I know about some of the "mechanical" words....

Im not going to admit my score, but I didn't pass, but I did have trouble understanding the proper words in some of the questions!

Needs to study more I guess..

Yes, I managed 95% but it would have been more interesting if they had shown you the ones you got wrong together with their idea of the correct answer.

As you said, Ciaran, there were a number of anomalies. e.g. they ask about the force that produces rotation when none of the offered answers are forces. In another one they again ask for a force and the answers are all in pressure. It all adds to the confusion.

Has anybody counted the number of questions so you can equate percentages against number of right answers?

Fascinating! I only got 84% but I also think some of the questions were ambigious, especially the one about gear trains. Where else I went wrong I don't know, physics was the only subject I was any good at, at school, but most of that I have learnt repairing cars.

Ah ha, Peter, I got 84 as well. However I'm not going to admit to one of the wrong answers I gave. Save to say a very red face.

If you click the little circular thing to the bottom left, it displays the list of questions and you can click on the previous ones to see if you got them right or not.

Another ambigious one was the thing about atmospheric pressure forcing the air into the engine, I surmised that the piston going down caused a vacum, and this is what actually allows the atmospheric pressure to force it's way in, but was wrong..

Ciarán

84% too.

90% but i defintely disagree with the way a couple of those questions are worded. (is air sucked into piston, or forced in by atmospheric pressure - one of the same or am i missing something?)

Just 80% for me. Must be faulty questions !!!!
I'm going back to have another try !

The 'atmospheric pressure' one I did get right! It's one of the few things I remembered from school. Our science master was always going on about it and I was the only one that got it right in the science test. which means I must have got something else wrong. I cant really see why they make all the fuss about it though, there has to be a vacuum to enable the pressure to do its stuff .

Peter.N.

I tried it again using the 'alternative' answers, and still only got 92%. I think its fixed!

Peter.N.

Hi all

I got 84% but dont know which ones i got wrong, interesting though.

The air pressure at the surface of the 3 different-sized baloons is well the same, isn't it??? Cannot understand why it returned this as "error".

George

Ah! It depends what they mean George. If they all have the same ammount of gas in them, the pressure will be higher in the smallest one, do they mean the total ammount of pressure over the whole area or pressure per square inch - not enough information!
