agreed it's like when you suck the air out of a bag or a plastic bottle. you aren't pulling in the plastic. you are removing the air pressure inside, and it's actually the air pressure on the outside which is crushing the plastic.
68% here, not as bad as id thought it would be, but not fantastic. a couple i answered incorrectly through not reading it properly.
74% so not a pass, but when you consider I'm studying accountancy you've got some idea of how mechanically minded I'm not. And anyhow, 80% that hellish high, only need 55% in ICAEW chartered exams!
It would if our printer worked, but unfortunately between us we're not mechanically minded enough to get it to work at the moment I have in another post somewhere - a Candy White Edition 30 GTI
Well done sir, and yes you're correct it is a little ambiguous, i was unaware that the inlet valve opened slightly later than the movement of the piston on the downward stroke, i guess i assumed that they opened whilst the piston moved down. Must read up a little more, the other stuff i got wrong was schoolboy errors. Was well impressed with the planetry gear question, just needed to sit back and think it out properly. Anyway. That's why i love this place! There is a mechanical knowledge far superior to my own to be tapped into.
70% not bad for someone in IT who knows very little about engines and didnt really pay that much attention as i dont have time!
82%. DOnt know a damn thing about electrics. although it seems more physics related then mechanical knowledge
Doh! My mistake! I mean the difference between the low pressure within the cylinder and the, therefore, higher outside air pressure (normal atmosphere).
I'm absolutly crap. People keep giving me gearbxoes, and in return I fill them with sawdust to make them quite. Go figure!
