the Equilibriums. In the Quadrature of a Parabola he assumes that, if a body
hangs at rest from a point, the centre of gravity of the body and the point of
suspension are in the same vertical line. Pappus states the same property with

It results, by a like argument, that the segment and the cone AEF taken together
where they are balance, about A, the cone AEF acting as one mass at H. Taking
moments as before, we can (since we know the position of the centre of gravity of
...

The centre of gravity of the inscribed figure necessarily lies on OA (Prop. 2), and if
there be two parabolic segments, and two figures inscribed 'in the well-known
manner' and with the same number of sides, the centres of gravity divide the ...
