WebMar 24, 2024 · Ellipsoid. The general ellipsoid, also called a triaxial ellipsoid, is a quadratic surface which is given in Cartesian coordinates by. where the semi-axes are of lengths , , and . In spherical coordinates, this becomes. If … WebSurface Area of the Spheroid In this section we derive the area of the spheroid, which is a surface of revolution. Draw the ellipse in the plane, spin it about the x axis, and apply the appropriate formula. Sounds straightforward, but the algebra gets a little involved, so hang on. Let an ellipse have semimajor axis a and semiminor axis b. A spheroid, also known as an ellipsoid of revolution or rotational ellipsoid, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters. A spheroid has circular symmetry. If the ellipse is rotated about its major axis, the result is a prolate … See more The equation of a tri-axial ellipsoid centred at the origin with semi-axes a, b and c aligned along the coordinate axes is $${\displaystyle {\frac {x^{2}}{a^{2}}}+{\frac {y^{2}}{b^{2}}}+{\frac {z^{2}}{c^{2}}}=1.}$$ See more The most common shapes for the density distribution of protons and neutrons in an atomic nucleus are spherical, prolate, and oblate spheroidal, where the polar axis is assumed to be the spin axis (or direction of the spin angular momentum vector).
