Bending Stress
Estimates the longitudinal normal stress in a beam based on bending moment and section position.
symbols, variables and units
M: N·m; y: distance from the neutral axis (m); I: second moment of section (m⁴); σ: Pa.
applicable conditions and boundaries
Linear elasticity, plane section assumption, bending around the main axis; symbols follow coordinate conventions.
