Did much better the 2nd time (79%) after I actually read through the questions.

My oldest nephew ran the nuclear reactor on the USS Abraham Lincoln at the start of the latest Gulf actions, and scored a 96%. He was sure he'd ace the test!

Duh, I'm glad that it wasn't a math quiz! 50 questions results in 2% per answer. Never mind.....

I got this from another group. Scored 60% and am afraid to take it a second time.

Engineer! Engineer! I got 80% and thought I did better. I agree that it would be nice to find what you missed. Paul Johnson

I got a 90, but then again, I did get a BSME so I guess I had an unfair advantage (actually a little embarassed that I didn't do better)

I got 96%

Some of the questions are poorly framed, like the one with the two boxes on an unequal seesaw. The "right" answer, which I picked, assumes the mass of the box to act at the end of its arm. The PROPER answer should have the lever arm's length defined by the box's center of mass.

The one I got wrong was the one with two fans. I think there's room for debate on that. Is the pair of fans acting as a fluid coupling, with the unpowered fan being dragged in the same direction as the powered one, or is it acting as a turbine, in which case it SHOULD rotate backwards, as the airflow is counter to that it would create if powered up.

maybe you missed the math skills Jim... 47/50 = 94%

Hell, I were an injunear,mechanical. Nevertheless, I drop the screw under the rotating plate when changing points, so who wood hyr mi?

Or what about the 'lectricity the "pushed" fan might generate...

Yep, their diagram didn't match the answers. My downfall was pulleys, I think, but I did score 90%.

Yeah... I got the centrifugal question with the green balls correct, BUT... if the connecting arms and center "hub" were "fixed" (non-moveable)..... it wouldn't do anything. They don't tell you if the center lower hub, or the upper one.... is floating

Ray ... 90%

BTW, you CAN see which ones you missed.... at the end, there is an icon on the right to 'review test'
