78% And I work on my own truck. Not much brain cells needed to fix it.

 

same here, i got a 62%. i looked at the ones i got wrong, some of those i should have got, and i am a mechanic by trade.

that is correct. balloon A was the smallest therefore balloon A had the higher atmospheric pressure.

 

These are pretty much what they ask you on the ASVAB test to see what job you could possibly get in the military service.

 

86% here, wish I would have known about the magnifying glass before hand.

 

92%. The weight and pulley questions got me a little confuzled.

 

That would be the atmosphere pressure on the outside pushing air into the cylinder. There is a vacuum or lack of pressure inside the cylinder. It does not get "sucked in" as it does get pushed into the cylinder.

 

yea I know... I didn't even think twice about it when I answered it gets "sucked in." Afterwards I was like "Duh." Tricky Tricky...

 

86%, and several of them were not very good questions. The piston sucking or atmosphere blowing is a good example. Depends on your frame of reference. (There is no such thing as blowing.... the whole world sucks)

 

That was just like taking a block exam , which i have done three of , i got 97%

One more exam like that , and i get my mech license

 

96%.

I don't know which ones I missed but I did not agree with the available answers on a couple of them. Like the balance one with the weights offset. The answers were for a five to one ratio but the drawing was a six to one ratio. The block and tackle one was too blurry to see for sure. It must be late.

A couple I didn't like either. As far as the multiple pulley one, the first pully was only changing direction. I had to really stop and think about that one for a minute! I didn't like the balloon one, but after thinking about it , and doing some research ( like it REALLY mattered! LOL) I see now what they were after. Again, the BEST answer out of available answers.

 

all though i felt i was doing ok i got through 23 question before i got a headache and quit lol

 

I got an 88, here are the questions I missed;

#7- I mixed up reverse and reduction, just placed them wrong

#11- worm gear

#19- this question is tricky, this display show's a vague image of a 4-1 haul system, but only 2 of the pulley's are moving, while the other 3 pulley's are simply a change of direction, from my quick paper scratching I came up with 50kg, the closest to my actual answer. I don't know, maybe the pulley size has something to do with further reduction?

#26- only 2 lights will light up

#32- B will be harder to move, I just over thought this one, (dee dee dee)

#44- The answer is higher in tube A, I picked B, B is on the high pressure side of the flow, pressure is what makes lift, turn your garden hose on all the way without a nozzle on the end of it then measure how far or high the stream goes, then close the valve half way to reduce the flow rate, then put you thumb over 3/4 of the end to restict the flow and measure how far or high it goes, it will self answer.


I am not sure, however, I believe that the Ford Doctor is the same individual that frequents The Diesel Stop, if in fact it is the same person I have had the opportunity to discuss issues with him via forum exchanges,
He is a excellent Ford, I/H tech, and always came up with thorough, correct answers, A valued resource for the members over there.

that was embarASSing!!! acouple i could just smack myself for after looking at it again some others i am still just confused on

 

96%. Woohoo!
