Could you please upload y-axis video as well. Thanks

sir can you do a video on getting y bar?

So if (5.08, y) is the centroid, how can the y-coordinate be found? Love your videos by the way, they're saving my life this semester!

You can find the y coordinate by doing the exact same process, just switching every instance of "x" with "y"

Hi! Thanks for making these informative videos !! They really help. But I am getting stuck on one concept. How do we know when to use which centroid formula for a triangle ? Why didn't we use the 1/3 b for the centroid as opposed to the 2/3b? What is the main difference? Thanks for all your help.

the smaller side I believe you use the 1/3 and the bigger one you use 2/3 when you divide the triangle from the middle

hye if the triangle is upside down. for y bar i need to use 2(b)/3 again? because it will start from the shortest one?

If the triangle was flipped vertically, the short side would still be on the left, so the calculation would be the same.

Sir, when will xbar or ybar for the centroid of a shape be equal to zero?

X bar will be zero if the centroid lays on the y axis. Y bar will be zero if the centroid lays on the x axis.

Thanks, but yeah that was my bad. I didn't bother because at the time when I made this it was a just precursor to simple distributed loading problems wihh vertical loads in which the y bar is never needed, but it could be for sloped members or wind/pressure loading etc... So whoops sorry!

Why isn't the x of the semi circle 0 here?

@Engineer4Free

5 жыл бұрын

The center of area of a full circle is in "the middle." Just draw a semicircle by itself and try to locate the "middle." You wouldn't draw the middle touching an edge, it would be about where I have drawn it in this video. Make sense? circles and semicircles are different shapes.

What will be the y coordinate of the Center of mass of semicircle

@Engineer4Free

5 жыл бұрын

The the centroid of a semicircle is 4r/3π away from the flat edge, and halfway between the top and bottom when it's oriented like this. y coordinate is therefore r away from both the top and the bottom

for a triangle in this orientation, centroid is 1/3 base away from the bottom right corner, and 1/3 height away from the bottom right corner.

The shape on the right is a semi circle. It is 3 units tall (see y axis). That means the diameter of the (would be full circle) semicircle is 3. Radius is 1/2 diameter, = 3/2 =1.5
