1.1 General theorems of rational dynamics

Starting from the elementary dynamics of the material point, the fundamental theorems are developed for any translational and rotational system. The first way to apply these theorems is to calculate the real mechanical power of applied forces and inertia.

Two main elements are developed:

• the decomposition considering, on the one hand, the motion of the center of mass (affected by the total mass of the system) and, on the other hand, the motion relative to the center...
