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
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
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
He explains question 5 as the answer being anticlockwise, but the text in the box isn't explained very well.For the most part the test is a good start for people.
I think you don't have sufficient knowledge about mechanics that's why you're saying that option A is correct which is not, the correct one is option C "point B".if you want to know it, let me know.then I'll help you
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.
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 :)
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
Thank you so much for this! :) I actually only scored 6 out of 10, but that's a good thing. I'll practice, learn, and be better in the end. Have a great weekend. :)
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.
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
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)
on question 5 You say that the answer is A. Anticlockwise but according to the choices on the screen answer A says clockwise and answer B says Anticlockwise.
Got 10/10 but I got lucky with question 4! Great videos Richard thank you I'm using your free download to practice before my online test. Wish me luck, :)
Question #10 is correct, but there's something missing in that explanation, the MASS of the beam. This is the torque question that follows the formula: Tcw = Tccw in which Tcw is the side where an object spins clockwise and Tccw is where the other object spins counterclockwise. Basically, Torque = r*F where r is the radius or length from the fulcrum of the beam to the object and F is the force exerts on a particular side. Based on the given information, we can calculate the Tcw that Tcw = 20*9.8*2 = 392N which means the other side must also equal 392 N to balance the beam. Now I noticed that the mass of the beam at this point has been neglected in this problem because what I did for the Tccw is I replaced 10kg into the equation Tccw = 10*9.8*2 = 392 N which is the correct answer. However, what I did at first was writing down the formula and tried to come up with a number to fill in the mass of the beam: Tcw = Tccw 20*9.8*2 = Mass of the beam*9.8*1 + Mass of the finding weight*9.8*4 392 = Mass of the beam*9.8*1 + Mass of the finding weight*9.8*4 If the mass of the beam isn't neglected in this problem, this problem has to be done in this way. This is my opinion, I'd like to hear anyone comes up with another way to solve this problem or correct me if I'm wrong at some points.
I downloaded the "free guide" but only got 8 pages of tips and 4 questions on pulleys that contradicted what was taught in the video as far as the amount of support ropes. On page 8, in the last paragraph, it said "It’s now time for you to try out the sample tests that I have created for you. There are twenty questions in each test and you have twenty minutes to complete each one of them. Answers are provided at the end of each test." Where are they?
Hi I just took it , and I got a 6 right and 4 wrong out of a possible 10.... I really want to do this which is locomotive Engineer for NJT. So many people applied that they closed testing I know I applied before they closed it. The last I heard on my bday in November. I'm praying I can study and prepare and get a call back .
I am pretty sure that question 2 is A, both the same. MA is all about how many supporting ropes there are on the weight. in the digram it is clear that the weight x has only one supporting rope being pulled up and that rope section b and a merely change direction of the applied effort. thus they must both be the same. In your mechanical compression free download question one is essentially showing this diagram without point a and the mechanical advantage answer is 1 too, so maybe its an error or I have just got it totally wrong? I would appreciate it if you could reply adding your view.?
I have interview in up coming months... I have to study specific topics related to interview .. In that general technical is there... means what I want to study about. That topic.
There is no mechanical advantage in Q2. The only advantage of a simple pulley system is just the direction. You pull the load up, by pulling the rope down. But, I believe you need an effort equal to the load lifted. Unless there are parts to the diagram that is not shown
I believe your correct . 1-1 ratio pulling down or out to the side . The pulley would have to be floating to gain the 1-2 advantage not sure why the video maker hasn't addressed this.
I answered them all correctly except Q2. I disagree with Q2. I think it would take the same amount of Force to lift from both A or B. I don't think this is a mechanical advantage of 2. But in reality, gravity would be on my side at point b. So it would be easier to let gravity pull me down and help lift load. It's physically easier to use my own body as a counterweight at b. I still think it would take the exact same amount of force to lift x from b or a or x The direction of force is changed but there is no mechanical advantage except the ability to add counterweight amounting to the same amount of force required to lift x from A B or X.
You probably didn't miss it because they provided an incorrect answer. With a fixed pulley as shown in question 2, the pulley should only change direction of required force, but provide no mechanical advantage. The correct answer should be A: Both the Same.
You show #5 as the answer was A: anti-clockwise...but the multiple choices has ant-clockwise as option B... So yes it is anti-clockwise but the choice for that us B
Indeed it is! With a fixed pulley as shown in question 2, the pulley should only change direction of required force, but provide no mechanical advantage. The correct answer should be A: Both the Same. The answer provided in this video for that question is 100% incorrect.
Hey mate, sorry to be a kill joy but question (2) has no advantage. A and B would require equal force. Not taking into consideration ones mass that would assist at pulling X up from point B. But there is no mechanical advantage. To lift X it would require X force from A or B.
For both the pulley questions, the answers downward and 75 kg, wouldnt there be non advantage because it is one pulley? I would divide the weight based on the amount of pulleys i have. One pulley is no advantage, 2 pulleys is a 2x lift advantage and a 2x length to pull. 3 = 3x and etc.

Hahah, yes, you found the mistake. Hope the others all know it.
This got me too I was scratching my head. How does this video have so many likes with all the mistakes like question 5 aswell
He explains question 5 as the answer being anticlockwise, but the text in the box isn't explained very well.For the most part the test is a good start for people.

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 ❤
I missed 2, it was the anticlockwise ones but got the rest correct! I go tomorrow to take my test for industrial maintenance
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 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.
Question 5 had the correct answer but the wrong letter key.
How do they not catch that?

Thanks a lot hopefully I can pass my test next Friday at Valero refinery in Houston
So did you get hired? I’m taking one for ineos.
How did your test go?
Question 5 I believe your typed answer is a typo. It reads a=anti clockwise but b is the choice for anticlockwise
thank you! your question number five give the correct explanation, but assigned it to the wrong letter option.
Thank you so much for this! :) I actually only scored 6 out of 10, but that's a good thing. I'll practice, learn, and be better in the end. Have a great weekend. :)
I got the last question correct. These questions were wonderful! Thank you for your video and link to mechanical advantage.
Taking the VST for the fire brigade tomorrow and this is just the best!!!! Thank you! :)

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)
Force acted upon the rope on X + Force acted upon the rope on B = Force holding the pulley.
i thought the same
I agree you would need a snatch block to make the mechanical advantages greater then the weight being lifted
For q2, I thought it has to be 2 pulleys to have an advantage of 2???
Awesome! Will be using the mechanical compression tests. I got more wrong than I'd like to admit!
mechanical *compression* tests??? LOL
Q1B,Q2B,Q3A,Q4C,Q5A,Q6C,Q7B,Q8A,Q9B,Q10A ,must remember to not panic and focus on questions.thank you big thumbs up!

Says the guy who got 1st answer wrong
Q5 is B
I got them all right, most thanks to your other mechanical video, and others to history channel productions.
get your invention done then!!!!
Great video I'm taking a test tomorrow thanks I passed with flying colors
on question 5 You say that the answer is A. Anticlockwise but according to the choices on the screen answer A says clockwise and answer B says Anticlockwise.
Got 10/10 but I got lucky with question 4! Great videos Richard thank you I'm using your free download to practice before my online test. Wish me luck, :)
in fact look up ther words discredit my test questions and you will see the answers in your own intellect, but thanks a millions still my bro.

This is my opinion, I'd like to hear anyone comes up with another way to solve this problem or correct me if I'm wrong at some points.
Good test to learn skills if you understand mechanical advantage a more then a novice don't bother unless you are very rusty
Q7 burned me but the rest were spot on. Thanks for the tutorial mate.
I'd never heard of a keelergram before, but I've head it used dozens of times now
Yes I got Q. 7 correct. These tests are very helpful and to the point.
Excellent! Glad you enjoyed
Thank you for the answer at the end.
Check #5 my friend. You correctly say ‘Anti-clockwise’ and have A listed as the answer….should be B, anti-clockwise
Man you gave the same example as question 2 in your mechanical comprehension and it had a mechanical advatange of 1
I downloaded the "free guide" but only got 8 pages of tips and 4 questions on pulleys that contradicted what was taught in the video as far as the amount of support ropes. On page 8, in the last paragraph, it said "It’s now time for you to try out the sample tests that I have created for you.

I only missed #9. Mainly because i don't really know much about planes.
you have said answer A clockwise for question 5. but in the answers A is clockwise and B is anticlockwise.
Yes it does im glad you saw it too.

I got #7 right but couldn’t get 9 and 10 definitely gonna be practicing more. I got 7/10 on this quiz
Lol q5 through me off because I knew I was right but re read what you said and it was a typo
I agree. Should be B.
Yeah, it's B!
Q5 you put a typo A=Anti-Clockwise, but B=Anti-clockwise. The answer is B, I though I had it wrong until I read everything again.I got 8/10

Thank you soo much
This helped me alot
I have interview in up coming months... I have to study specific topics related to interview .. In that general technical is there... means what I want to study about. That topic.
I didn't get question 6, but tbh if you look at the last question the thing is balancing without a weight on the other end...but I got that one right.
Hello, love the test. And I will use it and share. Thanks
I don’t understand second question. To pull A or B the same force. Why PointB is eaier?
Thank you for your video and explanation
You are welcome, if you want to try the questions and submit your answers, I will mark these for you?
There is no mechanical advantage in Q2. The only advantage of a simple pulley system is just the direction. You pull the load up, by pulling the rope down. But, I believe you need an effort equal to the load lifted. Unless there are parts to the diagram that is not shown
I believe your correct . 1-1 ratio pulling down or out to the side . The pulley would have to be floating to gain the 1-2 advantage not sure why the video maker hasn't addressed this.
I answered them all correctly except Q2.
I disagree with Q2.
I think it would take the same amount of Force to lift from both A or B. I don't think this is a mechanical advantage of 2.
But in reality, gravity would be on my side at point b. So it would be easier to let gravity pull me down and help lift load.
It's physically easier to use my own body as a counterweight at b.
I still think it would take the exact same amount of force to lift x from b or a or x
The direction of force is changed but there is no mechanical advantage except the ability to add counterweight amounting to the same amount of force required to lift x from A B or X.
I definitely agree with you
Great video! Need more videos like this!

I missed 2 questions.
Thank you so much for the explanation of the answers.
You probably didn't miss it because they provided an incorrect answer.

Woohoo, just started to learn this about a half hour ago, so far you have a great student, which in turn makes you a brilliant teacher.
The answer of Q2 is A, both the same.
Indeed it is! With a fixed pulley as shown in question 2, the pulley should only change direction of required force, but provide no mechanical advantage. The correct answer should be A: Both the Same.

Hey mate, sorry to be a kill joy but question (2) has no advantage. A and B would require equal force. Not taking into consideration ones mass that would assist at pulling X up from point B. But there is no mechanical advantage. To lift X it would require X force from A or B.

For both the pulley questions, the answers downward and 75 kg, wouldnt there be non advantage because it is one pulley? I would divide the weight based on the amount of pulleys i have. One pulley is no advantage, 2 pulleys is a 2x lift advantage and a 2x length to pull. 3 = 3x and etc.
Q2. Wrong. The mechanical advantage is 1 regardless of where you pull. The same amount of pulling force is equal from any angle of one pulley.
