Beam bending neutral axis
WebNov 26, 2024 · The bending moment acting on a section of the beam, due to an applied transverse force, is given by the product of the applied force and its distance from that section. It thus has units of N m. It is balanced by the internal moment arising from the stresses generated. WebBending. From the enlarged view of the linear variation of normal stress σ, we see that σ varies from zero at the beam s neutral axis to a maximum value, σmax at a distance farther from the neutral axis. σmax = the maximum normal stress in the beam. M = the resultant internal moment, determined from the method of section and the equilibrium ...
