FE Civil Exam Prep 35, Axial Stress and Strain, Hooke's Law, Poisson's Ratio

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 apply the fundamental axial stress formula, σ = P/A, and avoid common unit conversion traps between ksi and psi. - The critical difference between axial strain (ε = δ/L) and absolute deformation (δ), a frequent point of confusion on the exam. - How to use Hooke's Law (σ = Eε) to derive and apply the essential deformation formula δ = PL/AE, using the mnemonic "PLEA". - The concept and application of Poisson's Ratio (ν = -ε_lateral/ε_axial) to solve for changes in a member's cross-sectional dimensions. - How to integrate these concepts to solve multi-step problems, such as finding the final diameter of a rod under axial load.
