General beam bending equation
WebMore than One Point Load and/or Uniform Load acting on a Cantilever Beam. If more than one point load and/or uniform load are acting on a cantilever beam - the resulting maximum moment at the fixed end A and the resulting maximum deflection at end B can be calculated by summarizing the maximum moment in A and maximum deflection in B for … WebSep 2, 2024 · In pure bending (only bending moments applied, no transverse or longitudinal forces), the only stress is σ x as given by Equation 4.2.7. All other stresses are zero ( σ y = σ z = τ x y = τ x z = τ y z = 0 ). However, strains other than ϵ x are present, due to the Poisson effect.
