FE Civil Exam Prep 32, Rigid Body Rotation — Angular Motion and Instantaneous Center

Aug 5, 2026
This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - How to relate angular velocity (ω) and acceleration (α) to the linear motion of any point on a rigid body. - The correct application of the rotational kinetics equation, ΣM = Iα, for problems involving pure rotation. - The concept of the Instantaneous Center of Zero Velocity (ICZV) to dramatically simplify velocity analysis. - How to identify and avoid common exam traps like unit conversions (RPM to rad/s) and sign conventions. - The special case of rolling without slipping, where the contact point with the surface acts as the ICZV.
