    I scored an 84 twice,but the second time at least I knew how to see what I got wrong thanx to LIV42Day.LOL
     
  2. Hell, I thought "I was cutting a fat hog in the ass" I was up to question 32 before I got a message saying that a answer was incorrect. I didn't get another message, so I was feeling kind of smug until I saw the score 78%. Time to grab a big ole bite of humble pie.
     
  3. I got a 74%... I really have NO business building a car.

    this dumb old fart hit an 88, that's six wrong out of 50. Not bad for flunkin out of GMI cause of physics:)

  7. I got a 92. I wasn't sure on that one with about five pulleys stacked up.

    A couple questions had artwork that was a little confusing. Like the rack and pinion one didn't specify if the pinion was fixed or if the rack was fixed. Or the one with a "Piston" that looked like the head of a nail. Was the drawing representing fluid being pushed by a piston of that surface area to a smaller piston, or was that supposed to be a big nail-head shaped piston?

    86% for me. At least I passed. Probably could have done better if I had thought about some of them more before answering.

    I got a 66, the fan question is misleading. Same direction can mean 2 things, the same way literally, same way of the fan motor. Facing each other technically one would be counterclockwise and one would be clockwise.

    I also wasn't aware atmospheric pressure brought air into the cylinders, I always thought "suction" did it. Obviously not.

    The cylinder question got me also...I still say its suction:D

    They need a lesson on calculating percentages as well. I missed 16 out of 50. So I got 34 out of 50. 35/50 = .68*100=68%

    They gave me a 66.

    if you click the hour glass on your results page, it lets you go through it to see the correct answers.

    I say the question regarding the atmospheric pressure has technically two correct answers. Yes the pressure brings in air. Only because the piston pulling down creates the low pressure in the cylinder so the higher pressure outside wants to push its way into the cylinder. But yes the piston creates a sort of vacuum inside the cylinder. Thats my way of describing it.

    I took it as a piston, pushing onto a rod, or a "nail shaped piston". surface area was like 3 times more on top, so you multiply the pressure by 3, as you cut surface area down that much.

    It's like saying the fact the combustion chamber is actually pressured on the combustion stroke has not help on pushing it on the following exhaust stroke. I believe it does ;) Plus, the piston rings aren't letting air past them, or else there would be no compression, not constant anyways. Therefore it's PUSHING it out...same can be said for it sucking air in. Least that's how I see it.

    Once again while taking the test if you click the button to the far left of the submit button as you go through the test you can see correct and incorrect answers.

    As far as your percentage is concerned GrantH we do not know how each question is weighted. Some questions are much harder than others and may be considered 2 points instead of 1 or something like that. Go for the 50/50 and then it doesn't matter. ;-)

    But,,, because the pressure is higher outside it is pushing the air in.
    However I do agree with you, but I did learn it as things don't get sucked in, they get pushed in.

    Just between you and me....96

    I was lazy on the block and tackle and underestimated their understanding of things on the piston.

    What's the prize?
     
  27. 86. I think I really got 100, but 14% of the questions are wrong. hahahha

    You are correct. And I agree. I also got the question correct. There were just comments regarding "suction" in the thread. Thought I would toss in a small explanation.
