Resumen
This paper describes an alternative method for teaching undergraduate dynamics that has been usedin the Faculty of Mechanical Engineering at Technion for over twenty years. The sequence of topicsin the course presents the kinematics of particles, systems of particles and rigid bodies in threedimensions before discussing the kinetics of these systems. This alternative sequence provides thestudents with sufficient time and practice to master the concepts of a rotating coordinate systemwhich are essential for three-dimensional problems in dynamics. In addition, the paper presents adiscussion of indicial notation and tensors, a simple proof of the formula relating the time derivativeof rotating base vectors and the angular velocity vector, as well as a convenient tabular notationthat helps formulate complicated problems in dynamics. Two example problems are presented todemonstrate the use of this tabular notation.
