I HATE anything electrical….so that’s where no profanity please, masked or otherwise. mod up….lame….got all others except the how does air enter the engine one…I thought air was sucked in from the piston traveling down….lame!

Reason: profanity masking
Yeah, the naturally aspirated engine should be a combination of outside air pressure and a vacuum created by the downtravel of the piston (minus blowby pressure).
Sad to say, I got a 66%. I flubbed the gear questions like #7 and got the ballon question wrong (doh). Got the electrical stuff though except the three bulbs. I still think they would all light up. Going to have to test that one myself.
i got a 98 also. it told me the weight that was being pulled up over a pully was not the same as the weight needed to lift it. but i know i am rite, and the test is wrong. lift power only lessens if there is 2 or more anchor points, not one.
Got a 80%, stupid pulley questions. Maybe I should ditch the engineering degree and go for basketweaving.
Oh ya REBOCARDO- electricity will follow the path of least resistance, that why only two bulbs light up.

Actually, that is only with a fixed pulley, not one that is free...
Rebo, there were a few questions on there where knowledge of the Ideal Gas Law (PV=nRT) was necessary.
98 here too... That Naturally Aspirated question lacks the proper answer. atmospheric pressure, vacuum caused by the cylinder movement, and some caused by the exhaust gasses leaving(in the case of valve overlap) to some extent...
