integrating to find the balance point.

I don't understand why the first moment of integration doesn't balance the beam.

Anybody?

The first number (17.056 in) is the balance point, if you pick it up there it won't tip. I was mistakenly assuming that was where half the mass was on one side and half on the other; that will only be true for a symmetrical arrangement.

Need to be careful which point you want.

Yes, but I was puzzled, too, when I first glanced over your sheet.

You get equality if you take in account the distance from the centroidal axis:
