Online Mechanical Aptitude test

50 questions, may take you 5-10 minutes or 15 if you keep getting interrupted by actual work.

http://www.forddoctorsdts.com/quizzes/MechanicalAptitude.php

I got a 96%

When you get the results, there is a button somewhere on the page that is for reviewing the test. I think it may look like a magnifying glass, but I'm not certain. It will show you your answers and the correct answers.

I got an 84%, that's worse than I expected. Unfortunately I don't think they have published the answers.

Actually, when you finish the test there's a button for "review test" that does go through the test one question at a time showing your what you answered and what the correct answer is.

My attention span is too short for these games. I'm sure I would of scored in the high 90's, maybe even perfect!

86, but that's not really an aptitude test as specific knowledge of electrical symbols, hydrodynamics, etc..is required to correctly answer several questions.

Yes I bombed the electrical questions

Exactly. ..fairly easy stuff for any engineer. The only aptitude portion was in finding the correct answers JOHN.

heh heh, just raz'n your smartypantsness. I'm so glad that I don't have that problem.


The biggest problems come from the poorly worded Q's...

Here they explain a force and yet give units of pressure. (tisk tisk )




And then the Q I "got wrong" has an issue of relativity. If you reverse the flow over a fan, the rotation reverses as well. So the blown fan is running backwards (relative to its normal direction) but since it is opposing the other (blowing) fan, it is running opposite & opposed, making it run in the same direction (relative to the running fan blades) This leaves the reader guessing as to which is the relative reference. --the blowing fan, or the typical fan rotation direction. (other Q's were similar.)

I have to agree with island. There were several questions that were somewhat ambiguous. The fan one was a perfect example and I think I answered the same as you, but there were several others that struck me at the time.

92... the fan question screwed me over as well. They didn't define 'opposite'... as measured from what?

A very quick 90. I reviewed it and knew both questions I missed, just got caught speeding.
I guess there's no bonus for going fast?

The question about the brake, the mechanical motion effect is deceleration caused by a frictional force. Friction is a force, not a mechanical motion.

Oh, and a 90, 92 if you go with my answer for the brake.

I put the same answer that you did for the fan question.

I scored a 76, didn't check to see which ones I got wrong. I guess I will be labled the dunce of the class because I am sure no one will admit their score of 58.

Another question that's odd is the penultimate question about the air entering the cylinder. I don't see the difference between the downward motion of the piston sucking air in and the atmospheric pressure pushing air in. For example, if the cylinder was sitting there and not moving no air would enter the cylinder. Surely the real answer is the air enters the cylinder due to the pressure differential created by the piston moving down and lowering the pressure in the cylinder below atmospheric. So isn't either answer technically correct?

Technically they are both correct, but the atmospheric pressure pushing the air into the cylinder is "more" correct. Another bad question.
