Deformation of solid bodies under gravitation forces is of frequent occurrence and a subject matter of Mechanics. Usually calculations are performed for sphere-shaped solid bodies of a constant densit y. But if a sphere is compressed whilst its mass remains constant, a density is to increase in the process of deformation. Under these circumstances buckling and even collapse of a sphere are found to occur. Rotation of sphere-shaped solid bodies is also taken into consideration.
