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
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 :)
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.
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
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.
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)
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. :)
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
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.
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 .
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?
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, :)
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 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 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.?
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
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.
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.
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.
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.
I've read to your Mechanical Advantage PDF and it states there that to get the Mechanical Advantage, you will only need to count the Supporting Ropes, which means, Ropes that are supporting the Load. Question Number 7 explanation states that there are two Mechanical advantage, can you explain why it says two mechanical advantage when the supporting rope only shows one. Please correct me if I am wrong.
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.

@@modassirnazar7902 Please help me why the answer is C option Sir, I just thought the answer is A
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 missed 2, it was the anticlockwise ones but got the rest correct! I go tomorrow to take my test for industrial maintenance
Question 5 I believe your typed answer is a typo. It reads a=anti clockwise but b is the choice for anticlockwise
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.
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.
How do they not catch that?
thank you! your question number five give the correct explanation, but assigned it to the wrong letter option.
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?
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.
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
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
Q1B,Q2B,Q3A,Q4C,Q5A,Q6C,Q7B,Q8A,Q9B,Q10A ,must remember to not panic and focus on questions.thank you big thumbs up!
Q5 =C
Says the guy who got 1st answer wrong
Q5 is B
Q9 - A. Because headwind helps increase the lift of the plane.
I got the last question correct. These questions were wonderful! Thank you for your video and link to mechanical advantage.

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.
This test helped me understand the mechanical advantage, gear teeth ratio and wind direction calculation. I missed those questions.

you have said answer A clockwise for question 5. but in the answers A is clockwise and B is anticlockwise.
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.
Yes it does im glad you saw it too.
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
I got them all right, most thanks to your other mechanical video, and others to history channel productions.

Check #5 my friend. You correctly say ‘Anti-clockwise’ and have A listed as the answer….should be B, anti-clockwise

same for question 7
Not sure if I answered right I think I was looking at how box b was bigger
And not how the how much the object was tilted in which way
I don’t understand second question. To pull A or B the same force. Why PointB is eaier?
Thanks, this helped a lot!

So nice of you
I only missed #9. Mainly because i don't really know much about planes.
You've provided the right explanation for question 5 but the wrong Answer. It should be answer B not A.
Great video! Need more videos like this!
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.
love your vid i only got question 9
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.
