Torispherical heads with diameters from Ã¸ 500 mm to Ã¸ 5.400 mm and wall thicknesses of 3 mm to 30 mm. Ellipsoidal heads and elliptical bottoms with diameters from Ã¸ 600 mm to Ã¸ 4800 mm and wall thicknesses of 3 mm to 28 mm. Dished discs with diameters from Ã¸ 500 mm to Ã¸ 6000 mm and wall thicknesses of 3 mm to 60 mm.
If the ellipse is rotated about its major axis, the result is a prolate (elongated) spheroid, shaped like an American football or rugby ball. If the ellipse is rotated about its minor axis, the result is an oblate (flattened) spheroid, shaped like a lentil. If the generating ellipse is a circle, the result is a sphere. A spheroid has circular symmetry. Because of the combined effects of gravity and rotation, the shape of the Earth, and of all planets, is not quite a sphere but instead is slightly flattened in the direction of its axis of rotation. For that reason, in cartography the Earth is often approximated by an oblate spheroid instead of a sphere.
