A powerful geometric approach:

A short, fat block fails by crushing (yielding). A long, slender column fails by – sudden lateral deflection at a stress far below the material's yield strength. mechanics of materials 2

$\sigma_total = \sigma_axial \pm \sigma_bending \pm \sigma_thermal$ A powerful geometric approach: A short, fat block

Why solve complex differential equations when you can balance energy? are the foundation of FEA and advanced solid mechanics. A powerful geometric approach: A short

If you survived the first course in Mechanics of Materials (often called "Strength of Materials"), you mastered the fundamentals: axial loading, torsion, basic beam bending, and shear/moment diagrams. You learned to find stress ($\sigma = P/A$) and strain ($\epsilon = \delta/L$) in simple, prismatic members.

Failure in ductile materials (like steel) often initiates from shear, not tension.
