Centroid Parabolic area

    [SOLVED] Centroid Parabolic area

    1. The problem statement, all variables and given/known data
    Find the centroid of the area.

    2. Relevant equations

    3. The attempt at a solution

    I'm not quite sure what I'm screwing up on this problem, I can do other problems like when y = x^2. I have only shown my work for the x centroid, but I can't seem to get the answer (3/8b). Does anyone see where I messed up, I assume it's somewhere in the integral setup. I think dA = h-y dx is correct.

    The point (b,h) lies on the curve. Doesn't that suggest something, like a relationship between them, which you can put in the answer?
