Hello,
I am calculating the centroid of an area using this equation for composite bodies:
sum(indivudual area times individual centroid)/sum(individual area) = distance from axis to centroid
this is just y bar for a cross section that is symmetrical about the y axis
I was under the impression that when you find y bar, then the areas of the cross section on either side of y bar would be equal, but this is not the case. Is this correct and if so why?
I thought surely the centroid would mean there would be equal mass (or area in this case) on either side of it.
