    - The bending formula is given as (M/I) = (σ/y) = (E/R)

    here, M is bending moment, I is moment of inertia, y is the distance from neutral axis.

    - Pure bending or simple bending: When a beam is subjected to constant bending moment, no shear stresses are induced in that portion of beam.

    - Different assumptions considered during pure bending are:

    1) Beam used has constant cross-sectional area and is straight before the loads are applied.

    2) Material is isotropic and homogeneous

    3) It is subjected to pure bending.
