Chapter 18: Planar Dynamics of Rigid Bodies
"In Chapter 17 we analyzed planar motions of rigid bodies without considering the forces and couples
causing them. In this chapter we derive planar equations of angular motion for a rigid body. By
drawing the free-body diagram of an object and applying the equations of motion, we can determine
both the acceleration and of its center of mass and its angular acceleration in terms of the forces and
couples to which it is subjected."
