Engineering Mechanics: Statics, Fifth Edition

The topics covered in a course on dynamics vary according to the judgments of instructors and theobjectives of particular departments. Here we provide two curricula for basic courses that can be modifiedto meet the requirements of individual programs. The first curriculum is for a course that covers planardynamics of rigid bodies. The second one is for a course that includes three-dimensional dynamics ofrigid bodies.

Curriculum 2 — Three-Dimensional Rigid-Body Dynamics

After covering two-dimensional rigid-body kinematics (Chapter 17), three-dimensional rigid-body kine-matics are covered (Section 20.1). To avoid the need to derive the equations of motion twice, the Eulerequations are then covered in Section 20.2, which includes the derivation of the equations for planar motion.Planar applications are covered next (Section 18.4), followed by three-dimensional applications (Sections20.2 and 20.3).
