Just exactly how much mechanical aptitude do you have?

[Grizzly]

Passed, but not with flying colors.

well, that was a nice little warm up for the brain. . been out of school for a few years now. . 480/96% i got. .
#15 i had a brain fart on [dead weight & pulley]
#47 i messed up on [the governor] i was thinking the shaft was going to move down, and not the collar going to move, so i just picked the weights would move out. they had the shaft stay stationary and the collar moved up along with the weights. same total movement, but different stationary point.

Question 41 is nonsensical. They're asking what the force is on a piston face, but the answers are all pressure!? I assumed they meant what's the pressure on the face.



I scored a 92% doing the test "on the quick".



Screwed up the worm gear question.



Question 49 I knew the answer, but clicked the wrong box. So technically I scored 96%.



Got question 31 wrong... I'm a little iffy on their calculation. If we sum the moments at the fulcrum and assume the system is in equilibrium (so the reaction moment is 0), we get: Weight_b=300*(d1/d2), where d1 is the distance from the center of weight A to the fulcrum and d2 is the distance from the center of weight B to the fulcrum. Working that out, I get weight B is 1/5 of weight A. I must be missing something...

Wouldn't you just LOVE to see the mechanics and service manager at the dealership YOU use for truck servicing have to take that test cold turkey?



The results might explain a lot of the service quality and explanations for the issues we take the trucks in for... :-laf

 

[jmadden]

how could the fans be going the same direction? One goes forward... one goes backward... that's not the same direction;-) Or when you're between them... one goes clockwise and the other counterclockwise



I suspect over thinking may have impacted so of my score... even though it was passing.

 

[nickleinonen]

the fan question is basically a simplified torque converter/fluid coupling type of question. one turns, the other turns same way when looking at it from the end [even though one is turning cw, other is ccw, both turn down from the side]

 

[E7mack96]

dang, i am good

I just blew thru it and got a 96%.



Of the two I got wrong, 1 was from hitting the wrong button, the other was the level in the tube A or B on the hydraulic fluids. I will admit I wasn't sure of that answer.



so I say I got a 98%.



I feel good !

[robertyoke]

I got a 90% not bad for a carpenter. we aint the sharpest tools on the bench!

[tgordon]

94%, guess I have been looking in the wrong spot for a job, I should try Furd

 

[foolkiller]

fun test. 88%... . those pulleys were killing me but everything else, i think i nailed.

 

[Dl5treez]

On the grounds it may incriminate me, I refuse to give my final score percentage.



However, I will say that spending most of a decade in Ford dealership service had me take many a test extremely similar to that one... . :-laf

 

[TAbbott]

Got a 96. Shoulda aced it... . My bad. .

 

[CRuth]

Did it as fast as I could, got 70%. I"m happy with that as I've never had any formal automotive/technical training. Just work on my own stuff.

 

[catoiler]

got 1 wrong and it poped up a window that said wrong try again then got it right then at the last question after i hit submit it made a chime noise and went to a different test what gives?

 

[bb218]

Got a 90 on it, Fan question depends on which direction you are looking at the fan, missed that one. Also the one on the atomspheric pressure, pressure is same but amount each ballon sees is differrent. Fun test, Mike

 

[DCreed]

Take a look at a fan blade-- It rotates a certain direction to push air out. If you push the air thru backwards, it will rotate backwards. If you had 2 fans plugged in facing each other and unplugged one, it would stop pretty quickly and reverse its rotation.

you're exactly right!, but because the fan is turned around to face the other it is then going to turn the same direction when off. tricky.

 

[jwgary]

96% here too. #8 planetary gear, I mixed up the terms turning and rotating... I knew which way it went. #44 water through pipe, I thought you would create suction with the low pressure through the venturi so I said B wouldn't rise at all... I guess I though about it too much. Like TAbbott said, I shoulda aced it. That's all first year mechanical engineering/physics stuff. Fun exercise though.

 

[fest3er]

94%. I got #8 wrong - couldn't picture the gears right, #24 wrong (doh!), #48 - atmosphere does push, but it's because the piston is creating a vacuum . It only took 15-20 minutes...

 

[nickleinonen]

atmosphere does push, but it's because the piston is creating a vacuum

that is the catch with that question. that style of question was one the teachers at school always nailed someone with.

 

[Sri Ram]

80% or 400 points. Not sure how many I got wrong. I was only alerted to one wrong answer. Still fun, though.
