I don’t take statistics now I already finished it 2 years ago and still watching your videos. Thanks and keep up the good work

I’m really confused of this one. Wouldn’t y bar for shape 1 be 100 since it’s a triangle and 1/3 from the base? And Z bar 26.7?

DR. Hanson, thank you for a solid review on Centroid Composite Shape. Students in Statics/Dynamics have to do many problems in order to master these type of problems.

how the y bar of the triangle portion become half of 150mm?

[NorfatimaHAli-cslw]

I'm hoping someone to reply on this, but why did Prof Jeff find ybar and zbar on shape 1 using rectangle, isn't it triangle??

Quick question - the book shows that finding the centroid of a quarter circle is actually (4r)/(3pi). Is that correct? You show it to be 2r/pi

[Vezion_]

Shouldn't the area of 1/4th of the circle be (pi)r^2/4
