Statics - Centroids of Composite Shapes #1

[@sardarhammadsardarhamad6939]

Amazing video ever found on youtube .It solved my question in engineering mechanics .o

[@muktarhussein948]

5/48 determine the x and y coordinates of the centroid of the shaded area. Problem 5/46 thanks again!!!

[@Christofboy1Vlogs]

Which book are you referring to?

[@AhmedAdenOmarDaule]

total perfection!! thank you

[@mitchellemavesere7563]

Thanks man this question was explained by my lecturer and l never understood it

[@halilcankaya3202]

thanks you saved me in static exam.

[@Christofboy1Vlogs]

Aviator 737 No problem

[@jadlervincent3670]

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

[@wahabakinwunmi597]

Sir why do we had 12 when we took 1/3 of the triangle base ? Pls sir

[@dillmellojohnson6842]

Thanks for the turtorial and Please help me, I want to know why Xi of the 4 shape is 12 ?

[@johnkuhlmann1999]

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

[@muhammadmuneeb4108]

why you always take 1/3 of the Xi for the other shapes

[@Christofboy1Vlogs]

For right triangles, the centroid is 1/3 the distance from the right angle.

[@gilbertjunior824]

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?

[@Christofboy1Vlogs]

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.

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.

[@Christofboy1Vlogs]

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

Thank you so much sir
