An Introduction to Three-Dimensional, Rigid Body Dynamics
Below are links to a set of PDF files which together provide an introduction to three-dimensional, rigid body dynamics. The files are separated into two volumes. Volume I provides ten units of introduction to rigid body kinematics. The units of Volume II provide an introduction to rigid body kinetics. The last unit in each volume provides an introduction to modeling in MATLAB/Simulink/SimMechanics® (SimMechanics is now called SimScape Multibody).
The PDF files can be opened and read in any PDF viewer/reader application. In my experience, some of the viewers work better than others, so you may want to try different viewers to optimize your experience.
