The Simple Bending Equation applies to simply supported beams (and arches if the radius of curvature is greater than 10 times the depth)
Where:
- M = the Maximum Bending Moment
- σ = the Tensile Strength of the material (obtainable from tables or by experiment)
- Capital I = the Moment of Inertia about the Neutral Axis (for a rectangular beam this is its breadth times the depth cubed divided by 12).
- y = the distance of the Neutral Axis from the maximum stress (for a uniform rectangular beam this is half the depth)
