Bending Stress in a Beam Calculator

Bending stress is a measure of the internal forces that result from the bending of a structural element like a beam

• $\sigma$ is the bending stress,
• $M$ is the bending moment,
• $y$ is the perpendicular distance from the neutral axis to the point of interest (also known as the distance to the outer fiber),
• $I$ is the moment of inertia of the beam’s cross-sectional area.
