The calmness you have while explaining it, the methodology you use with perfection, it just couldn't be a better video. Thank you.

I appreciated this video very much mostly because it starts with the meaning of "balance" everyone "feels". Only after, it builts up progressively, and as a conclusion we get formulas, and we understand the "why" of these formulas. Thumb up, you care to explain well, I like it.

You have videos on literally everything. Thanks so much!

Wow this video was absolutely amazing. It really helped me get a better understanding of how we can use calculus in physics. Thank you so much

My life would have been a nightmare without you sir... you have my utmost gratitude

I don’t know if organic chemistry tutor will see this but please we really need video on centroid of composite shapes,then moment of inertia. Lots of engineering students are having issues with this. It would be really nice if you can come through for us.

I think you forgot the 1/2 at last example when you get the y-coordinate

Thnx Julio Gonzalez your the best teacher I ever had

🔥 This guy is too good. I wish you are able to tutor me in all my engineering courses.

love this vid, really useful. I just wish you did an example where there were the two lines didn't intersect. Like x=y^2 & x=1/2(y^2 + 1) in this case there are 3 lines that make up the area and i'm not sure on where to get the limits

I know this is calculus of course. But this application is really physics based as well. Doing angular momentum we have to use this very technique to start off. I know because we just had a lecture on this very thing yesterday. And wow, was I lost in class. Timing could not be better for this video. Thanks!

Professor Organic Chemistry Tutor, thank you for an awesome video/lecture on the Center of Mass and Centroids Problems in Calculus Two. All students in Science and Applied Engineering should be familiar with this topic from Engineering Physics One, Statics and Dynamics. This is an error free video/lecture on KZread TV with the Organic Chemistry Tutor.

Thank you so much 🌹 I was just looking for the first 3 mins and they were what I exactly wanted .

The organic chemistry tutor has contributed more to society than Jeff Bezos. Truly a saint.

There is a mistake in the last problem, y should be 12/5. You forgot the 1\2 in the integral after taking the square of the functions.

His hair WaCk, His smile WaCk, His calculus lectures WaCK, Organic Chem Tutor is tight af.

Can you give a reason why we can always find a horizontal line y=a through the lamina such that the sum of all the moments on either side of this line (ie the integral) is guaranteed to be zero. Or indeed why one can always find a line y=mx+c through the lamina where the sum of the moments on either side of it sum to zero. I know it's intuitively obvious (intersection of plumb lines hanging from different positions on the lamina in physics for example) but Id love to see a proof of this. Unfortunately I can't find an answer anywhere.

So helpful! Thank you

Do you not have to work out the integral before you multiply by f(x) + g(x)/2?

Its a great video...keep going sir

38:02 when he plugged in lower limit -2 as x, he didnt apply the multiplication of 2/9 outside the brackets.... why?

Shouldn't the area be 1/2? Because at 35:00 , the second part should be (8/3 + 4/2 - 4), instead of (8/3 - 4/2 - 4). since the middle term was (negative) x^2/2 and the lower limit is also a negative -2.

@joluju2375

4 жыл бұрын

The video is right, your calculation has a mistake. The lower bound is -2. If you square it, you get +4. Take the half, it's +4/2. The middle terme was the negative of that, so -4/2 is ok.

Pls I don't understand how u substitute m1y1+m2y3 pls where did u u get the numbers from sir...I mean this 8(5)+12(2) pls answer pls 🙏

how would we go about finding the centre of mass for a three-dimensional figure? would the z-coordinate be found in a similar fashion as x and y?

@meinUnishit

yes do it like usually but threat each coordinate as an individual thing.

Forgive me, my calculus is a bit rusty, but how exactly did you move the x into (from a to b) ∫(f(x)-g(x)dx at 22:23? Are we assuming that x is a constant? Or is this some other rule I haven't encountered yet?

wooow how amazing you are boy alot of thanksssssssssssss

22:26 Xi changes though for each strip, how can you just multiply the area/mass of the whole shape by just the X coordinate of one of the many strip's?

@gsairforce1482

4 жыл бұрын

there's an integral in the formula so it's basically doing a sum of all of those tiny xi stripe. That's how it works. You should check out the Riemann sum if you want to get a better understanding of the concept

ok, someone correct me if I am wrong here but at 40:04 the (1/2) just dissapears from the equation. We substitute A and then never add the constant before the integrand.....

@40:12 Where did “1/2 “ go?

why are you adding the formula to find yi inside the integral? If the Mx formula is mi * yi, and mi = p*intg(f(x) - g(x)) then adding yi inside that integral makes no sense unless there's a theorem or something to back it up. Shouldn't it be Mx = p * intg(f(x) - g(x)) * f(x)-g(x) / 2 ?

@satyapandya2034

3 жыл бұрын

Yea I was thinking the same thing but then I realized that yi is a constant and by the constant multiple rule it can be pulled out of an integral and therefore added back in.

@satyapandya2034

He says (f(x) - g(x))/2 but the x has a value so that whole expression is a constant.

you're brilliant👏👏💜💜💜💜❤💙

37:52 wouldn't the even power of -X^4 change the sign of x ?

Life saver🥺🥺

Sir on your last example I thin you forgot to put 1/2 on the formula or am I wrong XD hehe

Correct me if I'm wrong, but Moment is defined as rxf, r being the distance from the point you're focusing on, and f being the force applied. It simplifies to basically be torque (force times distance), but mass isn't a weight so how can they be the same

@Biggyweezer69

4 жыл бұрын

If you assume gravity is constant at every point on the lever/masses it can be ignored, since it will be the same for both moments, when comparing them it will be divided out. If gravity were different on one side of the fulcrum you would need to take that into account and use mass not weight. :3

@joluju2375

4 жыл бұрын

I agree with Otaku Fam. In order to find a center of mass, we compare things. Whether you use distance*force or distance*mass for a comparison is of no importance, just because it's only a comparison. I mean (D1*F1)/(D2*F2) = (D1*F1*g)/(D2*F2*g) = (D1*M1)/(D2*M2)

I also did'nt understand at first. Only later did I realize he first calculated the inside of the square brackets [(...)*(...)] and only after he wrote the x that was in front, like this x*[(......)]. I agree it's desorienting.

this is calculus 1 right?

still dont understand what is the different between center of mass and centroid

Integration DX/2+x

unsure what center of mass about axis means?

@joluju2375

4 жыл бұрын

Center of mass by itself has a physical meaning, and also it's a point. Now, a point has a location, given by two numbers. If you talk about one number only, you have to tell which one it is. You can say it's x, or it's y. You can also say it's about the X-axis, it's like saying it's y. And vice versa.
