Abstract

As for the planar case a set of coordinates are needed to describe position and rotation of the bodies in a spatial mechanical system in order to describe the kinematics. For the translational coordinates that is fairly straight forward, as it merely requires an extra Cartesian coordinate, z. Therefore the position vector r i for a body i becomes
$$ r_i = \left\{ {\begin{array}{*{20}c} x \\ y \\ z \\ \end{array} } \right\}_i $$
(2.1)
For the rotational parameters, however, it is more complex. Since rotation around more than one axis is not commutative as will be shown below; it is not sufficient to add the two additional angles around which the body can rotate to the vector of coordinates.
