Great test got a 96. Sent the test around work got some real surprises.

You would have to go back and take it again, but when you get your score, use the magnefying glass icon at the top right of the page and you can go back and review each question, your answers and the correct answer. Correct is green at top, incorrect is red and says incorrect.

Ron,

If your talking about the same pulley question I am thinking of, 3 pulleys on top and 2 on the bottom, the pulley diameter doesn't actually matter. The trick to it is that the tension in the rope is uniform and therefore must be equal to the force exerted by the hand in the drawing. The pulleys only change the direction of the tension force, not its magnitude. If you draw a horizontal line across the middle of the picture and "cut off" the top half of the system then 5 rope leads remain that support the weight. Because the tension is uniform throughout the rope, the total force applied to the weight is 5 times the force applied by the hand. The price paid for this mechanical advantage is that to lift the weight a given distance, the rope must be pulled 5 times that distance.

I always loved problems like that...

I don't know if I ever would have thought that through enough to have figured that out.I want to thank you for taking the time to point that out to me,what a revelation!! Now I can sleep again.
I can see the correlation to a series circuit and it makes sense to me now.Wow.
I was trying to analyze it based on gear reduction and I cannot rush into things like that,I get in trouble every time.LOL
I have learned something today.Thanks again.
Now that I typed all that I must confess that I printed the whole thing out so that I could gloat over the questions that I did get correct and the question that you are referring to I did get right.That was number 14.The one that gave me fits was number 19,"How much force is required to lift the weight?".
That is the vertical lift with 5 pulleys.Now I have to start thinking again:))
I guessed at the lowest number,25 KG for no particular reason as I did not have the presence of mind to think it through.It was a great test and an eye opener for me though.I needed that.Ron G

I had intentions of getting a high score until I realized I was going to be late for my job. I know "Goofing Off" on the computer! I messed up the multiple direction gear ones. I got an 80 though. Now I know I can go back I'll take it again. I too am going to send the link around work and let the "Geniuses" take it.

Just for Kicks, here is another test that covers a lot of subjects. It makes you get the right answer to turn the box color green. It stays red until you get the correct answer in the box. It can be a little frustrating as one can sometimes know what the answer is but one also has to word it correctly in the box. Have fun!!

jeeze M8
couldn't read it or uderstand it @ all
May B I left me brain sumwhere
dunno where but it'll catch up (I hope)

Th@ test must B for the other people th@ have lotsa brains

even on de udder test I only got 80

LOL

Swishy, I ain't got em all figgered out neither. Like number 19, I don't have a clue what that could be. (the line with the 4 x's on it) Some of the questions are pretty straight forward like the bevel gear, air, geiger counter etc. but some like 19 are a stumper for me. I figger since there ain't no time limit, I can take a long time to get a hunnerd persent.

Dont got nuthin to do with brains it has to do with serotonin, norepinephrene and the metabolic pathway for the polymorphisms!!

Correct answers with proper spelling:

1-infinity
2-decibel
3-capacitor
4-sine wave
5-geosynchronous orbit
6-diode
7-1 atmosphere
8-radio detection and ranging
9-thread pitch gage
10-geiger counter
11-or gate
12-speed of light
13-cathode ray tube
14-bevel gear
15-air
16-fillet weld
17-vacuum tube
18-molar gas constant
19-fence
20-laser hazard

I got 16/20 before I had to get help.

I didn't know:

11-or gate (computer programming logic circut symbol)
13-cathode ray tube (I thought it was cathode ray emitter)
18-molar gas constant
20-laser hazard (I knew it was a laser warning sign, but kept using the words danger or warning)

I ended up with 15 answers without help.I knew what 7 was but never did get it to like my answer.I knew 11 was a gate but not which one.
I never would have guessed 16 in a million years.I took it to be a solid state junction,maybe an SCR as close as I could tell but gracious,a weld???LOL.
I had to look up 18,didn't have a clue.I have seen 19 on plot plans and topos a million times but didn't expect to see it in this context.I had 20 as a warning about lasers but never did get the answer it wanted.Fun....Ron G
