ρ is the radius of curvature of the beam at its neutral axis. θ is the bend angle Since the bending is uniform and pure, there is therefore at a distance y from the neutral axis with the inherent property of having no strain: Therefore the longitudinal normal strain varies linearly with the distance y from the neutral surface. See more The neutral axis is an axis in the cross section of a beam (a member resisting bending) or shaft along which there are no longitudinal stresses or strains. Building trades workers should have a basic understanding of the … See more If the section is symmetric, isotropic and is not curved before a bend occurs, then the neutral axis is at the geometric centroid of a beam or shaft. All fibers on one side of the neutral axis are in a state of tension, while those on the opposite side are in compression See more Building trades workers should have at least a basic understanding of the concept of neutral axis, to avoid cutting openings to route wires, pipes, … See more Arches also have a neutral axis if they are made of stone; stone is an inelastic medium, and has little strength in tension. Therefore as the loading on the arch changes the neutral axis moves- if the neutral axis leaves the stonework, then the arch will fail.
