    - The deflection of beam depends upon its cross-section and bending moment.

    - The beam is designed based on stiffness criteria when the beam is strong enough to resist deflection.

    - The beam is designed based on strength criteria when the beam resists shear force and bending moment.

    - To avoid breaking of beam within permissible limits, the beam should be stiff.
