Spend at least 15 minutes setting up your free-body and kinematic diagrams before looking at the solutions.
If you are looking for guidance on how to navigate the Chapter 16 solutions manual and solve these complex problems yourself, this comprehensive breakdown will help you master the core concepts. Overview of Chapter 16: Planar Kinetics of Rigid Bodies
(horizontal). The intersection of these perpendiculars fixes the Instantaneous Center (IC) at coordinates Distance from IC to A: Distance from IC to B: , you can directly compute Step 3: Relative Acceleration Link the points vectorially: Spend at least 15 minutes setting up your
If you need the moment of inertia about a point other than the mass center, remember to apply is the distance between the axes. Misplacing : The inertial force vector must always be applied at the center of gravity ( ) , not at the point of contact or point of rotation.
has a normal acceleration directed straight toward the center of the disk ( It shows that the inertial terms —the -m
The chapter introduces D'Alembert's Principle, which reformulates Newton's second law as a pseudo-equilibrium condition. It shows that the inertial terms —the -m ā force acting at and the -Ī α couple—can be considered fictitious forces that, when added to the real external forces, create a state of dynamic equilibrium. This approach is powerful for drawing free-body diagrams that include inertial terms, allowing the use of static equilibrium equations to solve dynamic problems.

Chapter 16 introduces several fundamental principles for analyzing rigid body motion in two dimensions: Equations of Motion : Applying Newton's Second Law ( ) to rigid bodies. D’Alembert’s Principle : Treating the effective forces ( ) and inertial moments ( ) as equivalent to the external forces acting on the body. Kinetic Diagrams (KD)
