Mechanical Engineering Made Simple · Feb 4, 2026 · 42m · transcript

Mechanical failure isn’t just “it snapped.” It’s any change in size, shape, or material behavior that makes a part useless, even if it’s still technically in one piece. This episode is a practical framework for stress analysis and real-world failure modes, built for engineers who want to stop guessing and start predicting.

We break down stress and strain fundamentals (tension, compression, shear, axial and normal stress) and connect them to material behavior using Modulus of Elasticity and Poisson’s Ratio. Then we zoom into how real parts die: excessive elastic deflection, yielding, buckling…
