I took that test on another site,got an 82 on it.Humiliating.I got the electrical part just fine,the pulleys can get to ya,one of them I ended up guessing at.LOL
Some of the questions are not phrased properly and can get you in trouble and some have multiple answers so be sure and read them ALL before you select the proper one.It was an eye opener for me and I guess I needed it.😊
There were several replies on the forum where I found it and nobody aced it but there were a few in the 90s.I bet if I took it again..............Ron G😄 😄
I got 90, should have done better.
Not meaning to brag, but I got 98 on the test. What concerns me: Does this mean that I'm a Ford tractor man rather than a Cat man? Scary.😮
I got 86%
I guess I gave up kinda quick on some of the block & tackle questions...
I did this at work, so blew through it pretty fast...
Got 90%. Like to know which I missed.

I was under pressure to do something else and could not give it the concentration it deserved but the phrasing of the questions gave me my biggest percentage of mistakes.If you click on one of the icons at the top of the page you can review each question and answer.That pulley question with the multiple reductions was the one I guessed at and since it didn't say what size the pulleys were there was no way to accurate calculate the ratio without making some assumptions.I missed 9 questions.......rather correct answers.Ron G😮
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...
Great test got a 96. Sent the test around work got some real surprises.
