So What's Your Mechanical Aptitude ... A Test

[BusaLoco]

I found this on Oz Clubbies.

 

Mechanical Aptitude Test

 

I scored 81%

[eVox]

84% :]

[banjo29]

86%

[solder_guy]

88%

 

One of those Ser-Parallel questions threw me!

 

I may have to take it again to see if I can improve my score! :jester:

90%. on the fan question, I said opposite, because although they turn in the same direction, one is going clockwise, while the other goes counter clockwise. Probably got that one wrong.

[solder_guy]

Second time .. got 90% :crazy:

Yeah .. "as they are shown" is really vague.

96%. I think the engine question one is a bit ambiguous.( I answered atmospheric ) Otherwise though I thought it was fairly well written.

[Arya Ebrahimi]

Took this when prompted on another forum and got an 84%.

 

I found it to be very poorly worded and one could easily over analyze the question and get it wrong even though the answer is technically right. For example the 3 light bulb question with the switch bypassing one bulb. When that switch is thrown, the bypassed bulb will still light up ever so faintly, so I clicked 3 bulbs, but their answer is 2.

I need to get my wife to take this test so we can have someone score less than 80% :jester:

[locost7018]

Got 86%. Not too bad for an old guy, Russ

What if she aces it? :lol:

[Birkin42]

96% first try.

I know I got one electrical question wrong. Not sure which other one.

I answered suction from the piston going down on the intake stroke.

[Arya Ebrahimi]

They said atmospheric pressure was the answer for the piston question, which I think is wrong.

[yellowss7]

Alright, I'll fess up. I failed with 78% :cry: That's why I built a Caterham, it just bolts together. You guys that build your own from scratch are special. :flag: Tom

[Birkin42]

Air travels due to a relative pressure difference so who says the force to fill the cylinder is from the vacuum or from the atmopheric pressure. I went with the vacuum since it is the motion of the piston creating the pressure difference.

[xflow7]

They said atmospheric pressure was the answer for the piston question, which I think is wrong.

 

The one with the balloons? I agree.

 

I was 96% with that one scored Incorrect.

[ayseven]

I was not making this up when I said I had a lot of trouble with my car build. I got 70%.

I really tried!

[solder_guy]

They said atmospheric pressure was the answer for the piston question, which I think is wrong.

 

How do you get the answers??

That's the internet aptitude test.

Okay- I have to argue two answers- they always let me do that in school-

#48- 2 correct answers- atomspheric pressure does push the air into the cylinder, but the intake valve is already open when the piston starts to lower - of course the piston is 'sucking' air into the engine! I think my answer is more correct.

 

#47- bad diagram, what is the fixed point on this contraption? if I had known that the rod was fixed I would say the balls will move in a vertical as well as outward direction- but I thought the hub was fixed- therefore the rod would move vertically but the balls, attached to the hub, would not.

 

then i got two basic pulley questions wrong.

 

92% (In my world of physics its a 96%)
