x y V M x y 10. Beams: Flexural and shear stresses Objectives: To develop relationships for the normal stresses and shear stresses corresponding to the internal bending moment and shear force resultants in beams. Background: • The bending moment M and shear force V at a cut through the cross section of a beam are couple and force resultants of the normal and shear stresses, respectively, at the cross section. • Shear force/bending moment equation: V = dM dx • Axial stress/strain relation: σ x = Eε x Lecture topics: a) Strains for pure bending in beams b) Flexural stresses due to bending in beams c) Stresses due general transverse force and bending-couple loading of beams I I x Etf
