These applications are far from exhaustive, but we feel they are the chief representatives of problems for an undergraduate engineering dynamics course. As illustrations of the theory we consider four classes of problems: purely translational motion of a rigid body, rigid bodies that are free to rotate about one of their fixed material points, rolling and sliding bodies, and an imbalanced rotor problem.

As discussed in Chapter 16, when a body is subjected to general. SF ma where m is the mass of the body, and a the acceleration of G. The first equation defines the motion of the mass center G of the body. symmetric with respect to a fixed reference plane. 4 F G ma 3 F G The two equations for the motion of a system of particles apply to the most general case of the motion of a rigid body. Analyze problems involving translational motion. This decomposition, combined with the balance laws, can be used to prove a work-energy theorem for a rigid body. motion for a rigid body in planar motion. Although the underlying mathematical problems are similar, several solution methods have evolved, depending on the physical problems of interest. We then discuss the kinetic energy of a rigid body and establish the Koenig decomposition. The determination of rigid-body motion caused by incident waves is a familiar problem in mechanics. An alternative form of these laws is also presented that is useful for solving many classes of problems. These laws are known as the balances of linear and angular momenta. G mv2 1 2 I 2 + G 1 2 T G v G KE stored in translation of mass center KE stored in rotation Examples: Translation, FA Rotation r Fixed Axis Rotation O 1 2 I 2 T G v G 0 at O. We start by discussing Euler’s laws for a rigid body. This pdf file from IIT Guwahati explains the concepts and equations of plane kinematics of rigid bodies, with examples and diagrams. Work-Energy (WE) for Rigid Bodies Rigid bodies in general plane motion store kinetic energy in both translation AND rotation, so they have two KE terms.
