Saviour! !!!🙌 MuchRespect Sir
Sorry Sir but x2 value is 174.5
X coordinate for A2 isn't 175.5 rather 174.54
U guys should try to solve 200-[4(60)/3π]=174.54
And thats normal getting a different answer because of the discrepancy. I got (x,y) = (97.65 ,96.86)
ofcourse
Thank u sir for making such quality videos . Your teaching style is too good . You are too honest about teaching .You upload videos regularly . If any one will watch your videos regularly then he will be expert in engineering drawing like me . Thank u so much from my heart
I do not know who you are.
You taught me, but my professor said, 'take this as a Homework' and he leave.😞
Thank U sir. Do more videos👍
i have an engineering mechanics exam 2 days later and i am here to be sure i got everything or not. i am probably gonna watch every single video in this part. thank you so much for doing this.
As all sides are equal we need to take it as a square but you took it as a rectangle.
Just take it square from ur side
the value of x2=174.54.
It's not rectangle, it's square man
i am very thankful to you for your efforts...pls upload more videos for btech students..thankuh.🙏🙏🙏🙏🙏🙏🙏🙏🙏
Thanks abhishek..............more videos will be uploaded in future..........
thkuh sir..i was afraiding from my mechanics but now through ur videos . mechanics will afraid of me.
where are the centre of gravity problems
I just finished watching all the problems and I would love to thank you!!!
fantastic video, thanks!
174.535 is x2 for semi circle
sir i have a question , whilw calculating the area of the rectangle (a1) why didn't u subtracted the semi circle and traingle area????
Sir really u r giving wonderful teach ,each and every person should get easily. u r way doing problem each and every point u r presenting good .thank q
All the best.

isnt this (big shape) a square tho
Number is an square sir because x aixs 40+120+40=200
Y axis 120+80 so it's square?
What happens when I shift the semicircle downwards and I don’t know the projection beyond the edges of semicircle?? Will it be solvable??
Sir i can't understand x2
I think x2 =140+((4*60)/(3*π))=165.46 cm
Sir
Plz solve my Problem
Sir that is square not rectangle
Wait i dont understand why half of right angle triangle is that square? Why divided by 3?
😊
How to find whether your ans is correct or not
Sir ........what if there is a circle inside the square and not a semicircle......how do I solve for xc and yc
Well explained Now I complete my assignment
Can you explain mathematically why we can always find a line through a lamina (eg a horizontal line y=a in some coordinate system on the lamina) such that the moments on either side of this line sum to zero. It's intuitively obvious physically (hanging plumb lines etc) but I just can't prove this mathematically. The mathematics involves the integral of all the moments of every point mass of the lamina on either side of such a line, putting this integral equal to zero and solving for the coordinate of the centre of mass. But why can we always assume we can put such an integral equal to zero in the first place.
X axis is 200cm
Y axis is 120+40+40=200cm
Then it must be square not a rectangle
Yes you are right.........I got tricked by the shape. Glad that you pointed out.

X2 =51.32 value but you got 175.5 how sir once tell 😬🙄🤧🤧
How did you get 97.28
When i compute the Xc=i got 97.462
Sir here for the triangle, when we find the X position of the centroid, won't we take the measurement b/3 from the vertex between hypotenuse and the adjacent side, and if that is true then we will have to do (80 - b/3), ryt?
Thank you so much sir...its helping us great...may I have your mail so I can drop my personal question sir
2. Find the centroid of a semicircular section having outer and inner diameters of 200 mm and 160 mm respectively
please help me out sir
sir can u please find Ixx and Iyy of this question . Thank u for great teaching
sir can u plzzz solve a problem of centroid of a sector which is symmetric about y axis???
From morroco you help me thank youu
Sir I have the question but I can't sloveing it I am trying to slove but it not possible can u tell about how to retifie it plz
Can you say it once more while finding the x axis and y axis of right triangle
Is the is 3 coming from when finding x3 on a right angle triangle
Sir I am unable to solve one problem.please help me in solving that problem sir.
can u see check at x2 value once again . i have a doubt in that. please check value in any teaching there is no mistake
Sir i have a doubtt how can I post the photo ?? Please tell sir
area of a2 seems to be incorrect it should be 5652
Thanks a lot sir...
How do u determine which side of the rectangle is the base by just looking at it? The shorter side? ..Thank you for the video...very helpful😃
I didn't knew single thing about centroid untill i watch few of your videos. Thanks alot Manas. You are a legend
Thank u A lot sir🙏🥺 such a big help
What software are you using Sir?
But in trapezium que. We can also do by finding area of trapezium and subtract area of semi circle
Tysm😊
Thanks a lot Sir! You taught way better than my professor! Just done with my classwork. 🙏🙏🙏
very helpful. Thank you for the detailed explanation
Thanku sir.... It's really useful for us😊
Life saviour🙏
Thank u sir☺️☺️☺️
Thank you so much for your help! I got it right away!
It is 2/3*b not just b/b
Brilliant vedio sir
Hi Rahul.........
Thanks for appreciating my work and do spread a word about this channel among your friends and classmates so that they can also benefit.
Tq u very much sir I am clearly understood by ur teaching
Perfectly prepared for Tomorrow's exam ...
Thankyou Sir ..😍
Thank u sir
Very very usefulll🥰👍🔥🔥
if the question's values are given in mm, do we have to change it into cm ?
Best class
Thank you so much! This is what perfect teaching looks like!
Thankyou sirjii
give this man a bells
Much respect to you sir . Thanks a lot
Dear teacher, I am grateful to you.you have done great job for us.
Sir my ans of Xc is 97.65 is it ok plz rply..
Ya its correct... Same as me
200-(4r/3π) is equal to 174.5 not 175.5 :D
{5:31}
true , i am getting the values as y=90.25 and x=97.648
Thank you so much sir
Thank you a lot of sir❤️❤️❤️
1st viewer and commenter
I really don't know what to say, but I can tell you heartful thanks sir
All the best.

Super sir well teaching like coaching faculty
Which coaching provides Digital Education like this..... Do let me know?
@@ManasPatnaikofficial sir I'm not talking about digital teaching sir rather I'm taking about your way of teaching.
It's the best ways

i am confused on how you get your x2?
Well I can only say that you need to watch the video again I am sure you will be able to work it out yourself
Thanks sir
very good and can you make more videos

I got different final answers for x and y.
x=120.42 cm.
y=103.30 cm.
Idk but we got the same solution and values.
Thank you for your response sir!
