**Flexural Stresses: **Theory of simple bending – Assumptions – Derivation of bending equation: M/I = f/y = E/R Neutral axis – Determination bending stresses – section modulus of rectangular and circular sections (Solid and Hollow), I,T, Angle and Channel sections – Design of simple beam sections.

**Shear Stresses: **Derivation of formula – Shear stress distribution across various beams sections like rectangular, circular, triangular, I, T angle sections.
