Some of the questions are bad and I think two of them are straight up wrong. Therefore, I scored a 96%.

couple pulley ones got me, the first electrical diagram, the two pipes with water rising (higher pressure on B?), 48 is worded ****ty, the fan one i got but wasnt a good question, i missed the last one and shouldnt have.
88 percent. must be kinda tired, plus i didnt google.
the one about the piston where it asked does vacuum suck the air in or atmospheric pressure push it down...

missed the pipes and a planetary one
i suck at eletrical stuff
which ones do you think were wrong john?
the piston one is kind of iffy....i think it should have been vacuum...
are you guys serious about the piston one. its right, maybe its a little misleading though.
the one with the gears (#7 maybe)
over drive, underdrive- i got
reverse, direct- i mixed up, but im convinced its their fault
the venturi (#44 maybe)
i understand bernoulli's principal and the venturi effect, but i dont think the fluid will rise in B. I understand where they are coming from since most illustrations of this effect show fluid rising in B and higher in A to demonstrate the pressure difference. if fluid rises in B, then that means that P2 is greater than PB and that carburetor, sandblaster, airbrush, etc. isnt going to work.
oh, and the one with the see saw and two blocks where the fulcrum is offset. i dont remember the details but they didnt have the correct answer there. i just figured out what they did wrong when calculating it and picked the answer they thought was right.
What was the right answer on the piston one? I picked atmos pressure but I think its a bull**** question. I didn't see anywhere to view correct answers.
you can go back and look at them. it was atmospheric pressure.
on the gears i see what your saying about reverse and direct because technically the direct one is reversing the direction. however, 'D' is definitely not a direct drive.Quote:

that piston one is BS. Would atmospheric pressure be sufficient to push the piston down and fill the cylinder with air if the crank didn't pull it down? Fawk no, the crank is pulling the piston down, creating a void and vacuum which pulls air in.
If there was no atmospheric pressure, then it would stay a void.Quote:
