Excerpt from The Mechanical Principles of Engineering and Architecture The conditions of the dynamical stability of floating bodies include those of the rolling and pitching motion of ships. The discussion of the rolling motion of a cylinder includes that of the rocking motion to which a locomotive engine is subject, when its driving wheels are falsely balanced, and that of the slip of the wheel due to the same cause. The descent of a body upon an inclined plane when subjected to variations in temperature, which other wise would rest upon it, appears to explain satisfactorily the descent of glaciers.
