I’ve been watching your mechanical comprehension videos and I’m so proud to say I only got Q9 incorrect. Thank you for breaking things down in a simple way. I’ve learned more from your videos than I did with an actual book

8/10 although I would like to note the answer on question 5 is said correctly but is noted as answer A. In the answer list that is B. I'm sure it's already been noted in last 2-3 years but just here as a newbie :)

[adrienoropeza]

Q10: if you multiply what is on the same side and then divide what’s on the opposite side you get your answer.
(20*2=40)
(40/4=10)

I love this video so much. I’ve downloaded an ASVAB app to help me study but honestly, watching this made me feel less stressful. I love the attitude throughout the video and the explanation is on point! Thank you

[partan]

I love this way of you doing the lessons as we can get the answers right away instead of putting them in comments. Thank you so much for this help ❤

Question 5 had the correct answer but the wrong letter key.

[ETXKING]

I missed 2, it was the anticlockwise ones but got the rest correct! I go tomorrow to take my test for industrial maintenance

[mohammadnweylati]

For question two, I believe the correct correct answer is A "both the same "
Because the number of supporting ropes is only one in both cases, in anthoer word the mechanical advantage is one. If you pull the the rope from point A or B you need a force equals X

I got 10 for 10. Thanks for the great explanation on how each area worked. You simplified it and made it easy to understand what things worked the way they did.

Q1B, Q2B, Q3A, Q4C, Q5A, Q6C, Q7B, Q8A, Q9B, Q10A, must remember to not panic and focus on questions.thank you big thumbs up!

[beccapolk]

Question 5 I believe your typed answer is a typo. It reads a=anti clockwise but b is the choice for anticlockwise

[frederickchase]

Never been a "technical" person, mainly Admin but I managed to get 9 out of 10. Failed on number 1 through not applyng common sense. Will now have a go at somr more. Many thanks for posting them.

[joceywalters]

I got 5 correct and 5 incorrect. thank you for the practice I am preparing for the OAR to apply to be an Officer in the Navy

[romanweis]

thank you! your question number five give the correct explanation, but assigned it to the wrong letter option.

[strictlyscapey]

There were some questions where I almost got caught up in math, but at the last second was able to deduce the right answer through common sense. The question about the gear teeth most of it was me struggling to understand how to even approach doing the math for that, until I looked at the answers and realized it had to be 3 because it was a smaller gear and so would turn more and 3 was the only number there bigger than two. Same with the weights balanced at 2 and 4 meters. I didn’t know how to do the math, so I chose the only answer that was lighter than 20kg, which was 10kg. Then I realized that the mechanical advantage correlation was half the weight to the distance. I got 10/10

[d.s.]

The one I struggled with was the mechanical lift with a pulley. My assumption was that since the force was upward then I'd need at least more than the 75KG to lift. However it is really good to know the pulley to weight understanding. Thank you

[Khalid]

Q2 should be both the same. The pulley here is only transmitting the weight and there is no mechanical advantage (or you could say that the mechanical advantage is equal to 1, where both forces are the same)

[micahbrandner]

Good test to learn skills if you understand mechanical advantage a more then a novice don't bother unless you are very rusty

Thanks a lot hopefully I can pass my test next Friday at Valero refinery in Houston
