Summary:
(based on C. Truesdell's An idiot's fugitive essays on science: methods, criticisms, training,
circumstances and his introduction of Opera Omnia Series II, Volume 12)
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 looks at the 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.
More specifically, he considers
- ships in general;
- the equilibrium of ships;
- the stability of equilibrium;
- the oscillations of ships;
- inclination under the influence of arbitrary forces;
- the effect of rudders;
- the effect of oars;
- the construction of rowed ships;
- the force exerted by the wind on a sail;
- masting of sailing ships;
- a ship on a skew course.
