ENGINEERING MECHANICS (CE 101): Kinematics and Kinetics of Rigid Body
An Introduction to Rigid Body Dynamics
This chapter, Kinematics and Kinetics of Rigid Body in Plane Motion, Energy and Momentum Methods, explores the dynamic behavior of rigid bodies moving in a plane. It bridges the gap between particle dynamics and real-world engineering applications where bodies have finite size and shape.
We will analyze different types of plane motion—translation, rotation, and general plane motion—and learn methods to determine velocities using both absolute and relative approaches, including the concept of instantaneous center of rotation. The chapter introduces D’Alembert’s Principle for solving dynamics problems and covers essential energy methods including work-energy principles and kinetic energy calculations for rigid bodies.
Mastering these concepts is crucial for analyzing mechanical systems, machinery dynamics, and structural motions in various engineering fields.
