The most basic concepts involve forces applied along the longitudinal axis of a member. The internal force per unit area.
Torsion refers to the twisting of a structural member when loaded by couples (torques). Maximum at the outer surface ( Mechanics of Materials - Formulas and Problems:...
σ=−MyIsigma equals negative the fraction with numerator cap M y and denominator cap I end-fraction (Where is the distance from the neutral axis and is the moment of inertia). Occurs at the furthest fiber ( The most basic concepts involve forces applied along
