It is placed against a wall of a circular form, and thewater brought to it fills the buckets at the point A, and turns the wheel, partly by itsmomentum and partly by its weight. [ The most advantageous diameter of the breast-wheel will depend, like that of theovershot wheel, upon the height of the fall. It is obvious that the water does not actequally in moving the wheel, during the whole of its descent; for, as the power pro-duced by its weight always acts in lines perpendicular to the earths surface, its actionat A is in the direction A a, and therefore
