Content Summary

This is the second volume of a book enunciating—for the first time—the principles of hydrostatics. See the first volume (E110) for a general description of this book. In this volume, Euler describes some rules and precepts for constructing and steering ships. In Chapter 4, given an arbitrary floating body in various modes of oscillation, he calculates the length of an equivalent pendulum. This technique has become a part of modern hydrostatics. Some other topics he considers are: the equilibrium and oscillations of ships; inclination under the influence of arbitrary forces; the effects of rudders and oars; the force exerted by the wind on a sail; masting of sailing ships; a ship on a skew course. (Based on Clifford Truesdell's An idiot's fugitive essays on science: methods, criticisms, training, circumstances and his introduction to Opera Omnia Series II, Volume 12.)
