FE Civil Exam Prep 26, Resultants of Force Systems — 2D and 3D

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 resolve 2D forces into Rx and Ry components to find the resultant magnitude and direction. - The critical exam trap of determining the correct quadrant for the resultant angle based on the signs of the force components. - The extension of resultant calculations to 3D systems by including the z-component for both force and direction. - The key difference between concurrent systems (only a resultant force) and non-concurrent systems (a resultant force and a resultant moment). - That a couple creates a pure moment with zero resultant force, allowing its effect to be applied anywhere on a body.
