Text Published by World Scientific Press, October 1995
This book is number 17 in the series on Nonlinear Science edited by Professor
Leon Chua of the University of California at Berkeley. The book covers the
subject of multibody mechanics, that is the study of the dynamics of
interconnected rigid and flexible bodies. Problems and a disk of software to be
used with the Maple computer algebra system is provided. The projected selling
price is 43 pounds sterling.
The book was published on September 21, 1995. You can contact the publisher at the following

Corrections and Comments to Text as of November 1995
Chapter 1

Figure 1.4  The coordinates q1 and q2 should be interchanged in the figure.
Chapter 3

Equation 3.127  the q dot term should be transposed to a row vector.
Chapter 7

On page 293 the discussion of the linearized pendulum's phase plane contains errors.
The equations for the phase trajectory near the equalibrium points should contain
a constant. Thus for the stable point the equations are circles and for the unstable
point hyperbolas.
