Cause the y in the equation "ydashA=inyegrate (ydA)" and the Y coming from dA=Ydx are different .the small y denote all the particle in the shape while the Y denote the highest Y coordinate in each small rectangle considered during integration To relate y with Y we consider the rectanglular part in integration as uniform rod and first find its centre of gravity yL=intedrate(Ydl)(0,L) yL=(Lsquare)/2 y=L/2 Above L represent Y. Ps we misinterpret y=Y due to this when we integrate the particles in rectangular block use same y as that of highest Y present in the rectangular block
X co-ordinate is taken as 0 because of how he defined his co-ordinate axis In this case it's an isosceles triangle so if you divide it into 2 from the center on the y axis you get two equal halves Which means the x centroid is on y axis which is 0 on the x axis This only applies for this co-ordinate system. For other co-ordinate system it could be different. If we assume that the triangle starts from the origin (0,0) the x centroid will be at b/2 .
I'm gonna spend a whole day on it 103 videos on mechanics..
Thanks you sir
All the best Rahul...
Keep learning........
My best wishes are with you.....

Manas Patnaik thank you sir
May I get your mail id..
The way you and organic chemistry tutor explain is just brilliant. You guys are not fast nor slow. Brilliant 💯💯💯
Thank you so much sir, you are our saviour, keep up the good work sir.may god bless you
If a triangle is scalene then what will be the C. O. G. Of that triangle
Sir why did u take y/2 in the place of y?
Because centroid of that little piece in y/2
Thank you sir
May I know which book are you using ? Explanations are took good.i waana buy those....
Dear teacher, what is the abbreviation dA and what its meaning???
It's the area of the rectangular strip in red
Why y has been taken as y/2 did not understand
Cause the y in the equation "ydashA=inyegrate (ydA)" and the Y coming from dA=Ydx are different .the small y denote all the particle in the shape while the Y denote the highest Y coordinate in each small rectangle considered during integration
To relate y with Y we consider the rectanglular part in integration as uniform rod and first find its centre of gravity
yL=intedrate(Ydl)(0,L)
yL=(Lsquare)/2
y=L/2
Above L represent Y.
Ps we misinterpret y=Y due to this when we integrate the particles in rectangular block use same y as that of highest Y present in the rectangular block
Why we multiply the integration with 2
cause we are taking the limits for half triangle
Siirr thankyouu❤❤❤
Nice sir
hello sir...sir if u took the element in y direction ..the calculation could have been very easy
Thank you thank you so much sir 😊😊❤️🙏
Thanku Sir you clear it
Sir, but why x coordinate is taken 0?
X co-ordinate is taken as 0 because of how he defined his co-ordinate axis
In this case it's an isosceles triangle so if you divide it into 2 from the center on the y axis you get two equal halves
Which means the x centroid is on y axis which is 0 on the x axis
This only applies for this co-ordinate system.
For other co-ordinate system it could be different.
If we assume that the triangle starts from the origin (0,0) the x centroid will be at b/2 .
thanks sir
Sir can we find centroid of any laminar by using sqare differintial element
nice
Sir can you explain how
x^3/3 becomes b^3/8
u did not say complete proof
Well this is the lengthy one
it's not applicable for every kind of triangle. isn't it?
Why shouldn't taken along x axis ? What role of symmetry finding centriod or c o g in body
centroid is the point of intersection of 2 symmetrical axes of a geometrical shape
How we'll find CG of scalene triangle
Please clear why x=0? What if the centre of the base is not on(0,0)?
Because the figure is symmetric about Y axis which means x=0
Y axis ko middle ke koyi join kiya
Sir, in y^2 equation how did - 4h^2x/b come sir?
(a-b)^2 form bro
The way he says rise gives me a rise
Why c=h ????
th-cam.com/video/IL3UCuXrUzE/w-d-xo.html got it
Sir plz tell me.what about the book mechanics by NH Dubey?
I have come across Mumbai university students who refer it.... But personally I haven't gone through it.
Thank you! Sir
why can't we take along x-axis, plzz once solve along x-axis
It is not symmetrical about x axis
sir plz upload more numerical and truss problem where right side fixed
Roushan...Dont worry more problems will be uploaded....
Manas Patnaik okay Thank you sir
It would be grateful to us(student) if u solve the problem of *Irving H.Shames*"
Sir please give pdf sir.
Please sir give me ans 🔜🔜🔜🔜
Plzzz xplain clearly sir plzzzz
