rtbarton Posted November 15, 2007 Share Posted November 15, 2007 74% - I hate gears, my brain doesn't work on them.Phraseology for the intake stroke question. I didn't read the question on one (lever question about which would be more difficult) and after I clicked two I knew it was the other answer... Yeah, it would have been better if all the questions were visible at the same time. Quote Link to comment Share on other sites More sharing options...
Corrode Finger Posted November 15, 2007 Share Posted November 15, 2007 Umm, 76%, i am well chuffed, especially when i consider how well i did in A level physics............ U grade! Quote Link to comment Share on other sites More sharing options...

geoffbeaumont Posted November 16, 2007 Share Posted November 16, 2007 88% Questions 24 and 25 are the same circuit drawn slightly differently, but give different answers Got the worm drive wrong and hard to go back and stare at it really hard before I managed to convince myself they were right after all... Got a couple of pulley questions wrong, too, and the pumped constriction thingy, which I thought would act as a venturi. I'm still convinced that the atmospheric pressure on the outside of the balloons is the same - it's the internal pressure that's different?!! Ah...just reread the question Quote Link to comment Share on other sites More sharing options...
Fivespddisco Posted November 16, 2007 Share Posted November 16, 2007 Nice post. BUT 26 should and would be 3 light! and they where in series Quote Link to comment Share on other sites More sharing options...
Guest WALFY Posted November 16, 2007 Share Posted November 16, 2007 I am with you on the atmospheric pressure. ie all the same. Obviously didn't RTFQ properly :( Quote Link to comment Share on other sites More sharing options...
mike4444244 Posted November 16, 2007 Share Posted November 16, 2007 92% trying to remember physics from school did make my brain ache though... still, looks like i could go into orthopaedics after all mike Quote Link to comment Share on other sites More sharing options...
tacr2man Posted November 16, 2007 Share Posted November 16, 2007 I agree the intake stroke question debateable, 90% surprised remembered so much physics from school , long time ago now Quote Link to comment Share on other sites More sharing options...
BigSi110 Posted November 16, 2007 Share Posted November 16, 2007 80% and absolutely amazed that I got most of the electrical stuff right. That balloon got me too. Still, not that bad for someone who spends most of his time engineering pumps for oil refineries and the rest either using Autoglym's finest products or cooking.

rtbarton Posted November 16, 2007 Share Posted November 16, 2007 That balloon got me too. Yeah. I was looking at it as if the three balloons were in the same place at the same time, so atmospheric pressure would be the same on them all, so I couldn't understand how you got different amounts of gas in them and they were different sizes.

stumpy2268 Posted November 16, 2007 Share Posted November 16, 2007 74% If you see me rigging a snatch block - stand well clear, it could be coming your way Not done much of this stuff for 25 years, so I guess I didn't do too badly. Quote Link to comment Share on other sites More sharing options...
T1G UP Posted November 16, 2007 Share Posted November 16, 2007 82% I'm ok with that, a few bits i didn't really get and a got the 4 stroke engine one wrong cause i thought that the suction would assist the atmo pressure and so suction was the answer?!

will_warne Posted November 16, 2007 Share Posted November 16, 2007 94% but I have just got in from the pub But you weren't drinking I got 88% seems OK. I realised after the first few questions I got some of the early gear questions wrong Quote Link to comment Share on other sites More sharing options...
Astro_Al Posted November 16, 2007 Share Posted November 16, 2007 Saw this on the Mog forum. Good fun. Had a dizzy moment on the one with lots of pulleys Got 96% . Maybe I should go into brain surgery or something? Brains are diesel, right? Al. Anyone got any more? B) Quote Link to comment Share on other sites More sharing options...
missingsid Posted November 16, 2007 Share Posted November 16, 2007 88% so I am happy as I only did 3 years in college 33 years ago The bit I failed was finding how to review the questions Now I will have to do it again to see the mistakes. Shame there wasn't more electric ones Nice post thanks for adding it. Quote Link to comment Share on other sites More sharing options...
Superpants Posted November 16, 2007 Share Posted November 16, 2007 90% I do agree that a couple of the questions are a little ambiguous. Good amusement for a lunchbreak though. Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted November 18, 2007 Share Posted November 18, 2007 82% and I never was good at blocks and tackle! Or electrikle stuff. I would like to know which questions I got right and which wrong though. And they get 0/10 for spelling - the old principal/priciple one rears its ugly head again Quote Link to comment Share on other sites More sharing options...
Ryan Posted November 18, 2007 Share Posted November 18, 2007 I got 82% and I've got no electrical or mechanical quaifications whatsoever! ....actually that explains alot! "Hit it with an 'ammer!"

Milemarker Type S Posted November 18, 2007 Share Posted November 18, 2007 92%... Though can't for the life of me work out how to find out which ones I got right and wrong without going through all of them again... Am I missing something?

Milemarker Type S Posted November 18, 2007 Share Posted November 18, 2007 just click the review results bit at the end of the test. Doh Twas the fans (Still don't get why it would spin in the same direction? ), water being pumped through pipes and the 12 volt batteries in series and parallel (Glad I don't have a split charge system...) that were my undoing. Excellent link though, Ta Shrek Quote Link to comment Share on other sites More sharing options...
simonr Posted November 19, 2007 Share Posted November 19, 2007 I got 98% - so I guess I got 1 wrong. Thought some were a bit ambiguous. The one with a piston in a gas engine saying what causes the air to enter the piston. Is it the suction caused by the piston moving or the atmospheric pressure pushing the air in. Actually it's the differential pressure between the inside and outside, so both could be correct - but I went for the latter. Most of the rest of it was straightforward with a bit of thought. I'll give it a go tomorrow when I'm not drunk! Si PS The fans go in the same direction by the way. Imagine if both were turning in opposite directions as shown, they would both be pushing air in to the void inbetween. turning the same way (as shown), one blows and the otrher sucks. PPS Having reviewed the results, the one I got wrong was the planet gears one at the start. Case of mis-reading the options I think. Quote Link to comment Share on other sites More sharing options...

Why did I just KNOW that SimonR would score top marks? My GF (with no help) has just scored 78 and the ones she got wrong were things like the reciprocal to rotary one - where after all, if somebody hadn't told you it was called a crankshaft would you know? she got the fan right (and it was worked out).... Cripes I am impressed! TS Quote Link to comment Share on other sites More sharing options...

Excellent link though, Ta Shrek I considered the fans as srewed rod, with the air between as a nut. As the nut moves down the rod the latter must rotate in the same direction each side of the nut.
