FE Mechanical Exam Prep 85, Shafts Pressure Vessels and Piping Design
Nov 4, 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 separate and calculate bending stress (σ) and torsional shear stress (τ) in a shaft under combined loads.
- The application of failure theories, like Maximum Shear Stress and von Mises, to find equivalent stresses for design checks.
- The formulas and key differences between hoop stress (pr/t) and axial stress (pr/2t) in thin-walled cylindrical pressure vessels.
- Common exam traps including unit conversions, radius vs. diameter confusion, and the thin-walled assumption (r/t ≥ 10).
- A simple mnemonic, "Hoop is Huge," to remember that hoop stress is twice the axial stress and is the critical stress in cylindrical vessels.
