Im having a hard time getting my head around this, any help would be much appreciated.
1. The problem statement, all variables and given/known data
Determine the position of the centroid and calculate the second moment of area about a horizontal axis passing through the centroid for the following sections shown. Attached is the image of the shape, including dimensions.
2. Relevant equations
A x Y(bar) = (A1 x Y1) + (A2 x Y2)
IX = Ix + Ah(squared) [Not sure if this equation is correct]
3. The attempt at a solution
I know Y(bar) to equal 40mm for the attached shape. However i dont know how to get from the y(bar) to the position of the centriod. The answer should be 862000.0mm, i just dont know how to get there, everything i try comes up with a different result.
No one is guaranteed to get all of their questions answered. If you have gotten help elsewhere then good for you.
Note that if you are truly going to be upset that no one here answered your question, you could help out by providing a solution. Someone else might learn something from it, and you will have done something good. Think about it.
