Thought you guys might enjoy this.
Take the test and if you score over 90% then flame me!!:flipoff2:

I scored a 92 but it took me a long time to think through the pulley questions:shaking:

72% Hell yeah! Not bad for no schoolin. :homer:

88% i passed do i get to be a diesel tech now?
good test i liked it

wish i would have got one more question right so i could call you a fucktard :flipoff2:

x2

84% - Not to bad for an Economist.

88%. Would've done better if I actually paid attention to what I was reading. :shaking: :D

Cool test though.

I got a 78% which was a gift, because I had my roomate (physics major) help me on the pulley questions, but even he did not understand it, because the way it was worded was "incorrect" and he was just getting pissed, and I had my roomate from last year (electrical engineering major) help me with the electric shit

88%. Had I spent more time on some of them, I could have scored higher. Not bad anyway. I wish they'd show which were wrong.

I got 94%.

Our parts guy got 50%.

The wording was bad on several of the questions, like 'Same direction'....same direction, from what perspective?? counterclockwise from which side?

do you guys agree with the answer to #48 about how air enters into a cyliner?

Yea #48 Is questionable
You can't suck air.
The piston leaves a vaccum, then the air pressure from outside rushs in.
Still though kind of stupid question.

How about gravity...there would be no air pressure if it weren't for gravity...so how can it be due to pressure and not due to gravity?

do you guys agree with the answer to #48 about how air enters into a cyliner?

as to not give away an asnwer... black text below

well, since the cylinder is otherwise sealed except for the intake valve, the piston moving down is increasing the volume lowering the pressure. atmospheric pressure is then rushing in to equalize the pressure. the piston is not sucking the air in, its lowering the pressure.

to me its the same thing and i answered getting sucked in as well, but after thinking about it, the answer is atmospheric pressure.

HA, 88%!!! That is a very cool test. Oh yeah, very little mechanical background, only had highschool physics and about 4 weeks of physics 101 in college. (changed major)

In question 26 why wouldn't all three lights light up?

Tricky question, if the green weights on question 47 had no weight what would they do?

In question 26 why wouldn't all three lights light up?

Hidden below:

The middle light wouldn't light up because its easier for the electrons to go around it and use the closed switch instead. Figure which has more resistance: a closed switch (or just a regular piece of wire) or a light bulb?

In question 26 why wouldn't all three lights light up?

because the switch creates a short meaning all the current will go through the switch since there is no resistance and no current will go through the light

In question 26 why wouldn't all three lights light up?

Path of least resistance. meaning the current would rather go though switch then load.

88%

not bad for no schooling and not taking my time, i missed a couple stupid ones :laughing:

a lot of these questions are horribly worded/described....question 31 should be thrown out, the answer is 60 kg if the mass is evenly distributed, center of mass of block b is 5 blocks as opposed to block a which is 1 block so block b should be 1/5 the mass of block a

oh ok i get it, that makes sense.

In question 26 why wouldn't all three lights light up?

Electricity takes the easiest (less resistance) path possible. The electricity can go through the wire with a very low resistance or it can go through the light with a very high resistance compared to the wire. So, fallowing the laws of physics, the electricity goes through the wire and completely passes by the light in the center.

yea both boxes should be centered of the end the bar!!:shaking:

Crappy 82, thought I was smarter than that

78% cause I got confused on some of the pulley questions.

90 and some of the questios suck...:D

100% woooohoooooooooo the questions realy suck

86%:flipoff2:

I got a lame 82%.

Could have spent more time.:homer:

86 yea alot of the questions were a little confusing but i gues an 86 isnt bad.

I got a 98.:flipoff2:

If atmosphere is pushing the air in a cylinder, then why does a vacuum gauge read vacuum when in the manifold. Personally, none of the answers in that question were exactly right.

It's a shame that's all you need to know to work on Fords.:laughing:

Cool test. I got 80%

I thought I was gonna near ace it till I got to the electrical part. I don't know
shit about electrical symbols.

The first one about the lever, I couldn't figure out which side you were supposed to be lifting from. Is the triangle the hinge side, or the point where you exert the force?

X2, I was doing great until the electircal and then I went down hill fast! I do not like electircal stuff at all!

88% not bad for a IEEE.

92% but I missed almost all the elec.

got all the pully Q's :flipoff2:

The triangle represents the fulcrum (hinge) the closer the fulcrum is to the weight, the easier it will be to lift.

Oh yeah, 90% with a little 1 1/2 yr old bugging me.

74% - I guess that's what I get for having an Econ degree...

94% it was a tuffy

Damn you.... I was going to say "this is stupid" but I got suckered in (being an engineer I couldn't resist). I got an 86% but I made some STUPID mistakes. That's what I get for talking on the phone and not paying attention. At least I got all the electrical ones right (I'm a EE!)

M.E. grad student- 96%

can somone explain the reverse and direct on #7 to me

i think #44 is wrong but i can see where they are coming from. fluid wouldnt rise in B because it would be pulling a vacuum (i.e.- carburetor or sand blaster)

did anyone notice the fan one? even tho the fan is spinning the same direction as the fan with power, the other fan is backwards so technically isnt it spinning in the oppsite direction?

i got an 80% pretty good for a highschool student

i think #44 is wrong but i can see where they are coming from. fluid wouldnt rise in B because it would be pulling a vacuum (i.e.- carburetor or sand blaster)

#7 the driven gear (the last one) spins clockwise as opposed to the other three which spin counter-clockwise, so i put it as the reverse gear.

#44 doesn't flow rate have to do with resistance and path A has less resistance than path B..

86% for me. Pretty poor having taken college-level physics.

100% yay..... twice almost put the wrong answer for mis reading..... double check before you hit that submit button....
# 44 doesn't nesisarily draw a vacuum. it does however have less pressure in the second column because of the ventauri effect ... answer 3 COULD be correct if flow was high enough and pressure low enough but since not rising at all is less than rising some answer 1 will ALWAYS be correct
EDIT: now that I think about it this may not even be a ventauri ... kinda just looks like back pressure from a reduction in pipe size causing higher pressure in the first pipe...... awe fkit

took about the first 20 q's then quit. alot of the questions are quite veuge. like the ring and pinion one, clockwise and counterclockwise. it depends where you're looking on which one it spins.

i don't know, i guess i'm just used to axis :flipoff2:

-Kyle

94% - Mechanical Engineering Student

Went to fast and #48 is BS, two correct answers if you ask me.

Fun though

EDIT: now that I think about it this may not even be a ventauri ... kinda just looks like back pressure from a reduction in pipe size causing higher pressure in the first pipe...... awe fkit

fluid pressure always decreases with an increase in velocity, exactly why a venturi works like it does

yup... either way you get the same answer to that question tho since velocities and pressure aren't given

I got 80% i guess thats good for being 16 and teaching myself
