Please make more composite shape centroid videos
8:45 super random that now we have this formula 4/(3pi) * r when it's on the center of the origin. Is this the only time we would use that formula? Other times I see in your videos you just use the center coordinates of the circle x, y
🎉
Amazing😏
Sir why do we had 12 when we took 1/3 of the triangle base ? Pls sir
wtf that answer bro its 95.6
Thankyou
For the third shape the rectangle can you explain how you got 12 for x and 4 for y instead of taking half of 2 which is 1 for x and half of 4 which is 2 for y . Please and thank you
Thanks,but the answer is wrong it is 95.3, you made a mistake when you multipled area of the traingle twice, 2(X *A) but you {(2*X) *(2*A) }*it's wrong.
Thanks for this. I thought the same thing and looked through the comments for reassurance
You’re right.
Hey, Can you explain more?
@@captainchicken7650can you explain??? Please
@@Christofboy1Vlogscan you correct it for me.. I'm stuck here
Thnkssss❤❤❤❤❤❤❤
Thanks for the turtorial and Please help me, I want to know why Xi of the 4 shape is 12 ?
It's not, it should be 11. His Xc value is what I got and I used 11 not 12, I think he just wrote it wrong
Thanks man this question was explained by my lecturer and l never understood it
Thanks bro🥰
Sir for the yi of triangle how did you come up with 16/3 instead of 8/3 sir enlighten me plss
Keep in mind, the distance of the centroid depends on where your origin is. So the yi for the triangle is 4/3 (height is 4 taken to the 1/3) PLUS the distance from the origin to that triangle. 4” is the distance from the origin to the base of the triangle. Now all you do is add 4 + 4/3 to get your yi
4/3 (+4 from rectangle
@@Christofboy1Vlogs shouldn't it be 4+5\3?
@@akhonaradebe2688 not by the way I set it up. I allowed the triangle have a height of 4”
Thank you very much can you solve more problems like this ?
Hello sir, for the x centroid of the triangle why did you add the 12 to make it 14? I thought it was only b/3.
Recall that our reference point is the origin. So the centroid of the triangle is the distance from (0,0) to the centroid of the triangle
me and the boomer appreciate your effort, we have a statics midterm exam in 3 hours :)
Hoyyare mwone porich❤️...
if we find the X bar what is the x center of big rectangle particularly
Where is the rest of the playlist...??
ThanQ man
why you always take 1/3 of the Xi for the other shapes
For right triangles, the centroid is 1/3 the distance from the right angle.
great video
why we choose the horizontal line, not the vertical line as the moment of area
You can choose how you want to set up your differential area. The set up would be different, but leads to the same result.
5/48 determine the x and y coordinates of the centroid of the shaded area. Problem 5/46 thanks again!!!
Which book are you referring to?
Thank you so much
Thank you so much sir
ur answr is wrong its 95.6
I had 97.31
if the circular area is also shaded then what will v the centroid.....
only use (+) in area calculation
Thanks man
Pretty useful, thanks.
thankssss, you saved meeee
Really helpful man, Thanks 👍🏼
Thanks so much.. But do you have any videos on where the composite figure lies in the negative x and y plane Does it affect your xbar and y bar values?
Your coordinate system is key for determining the xbar and ybar values. If you, let’s say, change your coordinate system so that your x and y axis flip directions in this problem, you’d deal with sign changes for xbars and ybars (This also assumes you didn’t translate the origin of your system). The result should be the same if you work it out both ways.
Best video today!
Thank you
Amazing video ever found on youtube .It solved my question in engineering mechanics .o
Thank you sir
Vraj Panji You’re welcome
thanks you saved me in static exam.
