Strain due to bending, Civil Engineering

  1. Beam of arbitrary cross-sectionsubjected to couples M
  2. Bending moment at any sectionis M
  3. Consider segment of beam subtended by angle θ
  4. Some fibres will shorten e.g. ABand others will elongate
  5. The neutral axis DE representszero strain
  6. Consider strain in fibre JK distance 'y' from neutral axis
