... space in terms of three angles between axes that are either fixed in space or are attached to symmetry planes of the body’s motion. The three Euler angles, , and θ are generalized coordinates ... the reduced system. The trajec- tories on the sphere in Figure 1.3.1 are the reduced trajectories for the rigid body problem. We saw that steady rotations of the rigid body correspond to fixed...

... forces acting on a piece of material are of two types. First, there are forces of stress, whereby the piece of material is acted on by forces across its surface by the rest of the continuum. Second, ... w 2 )isthe square length of the vector function u. We assume that the total energy of the fluid can be written as E total = E kinetic + E internal where E internal is the...
