    - Curved beam: Neutral axis and centroidal axis are curved along with all fibers in a curved beam, when it is in an unloaded condition.

    - Brackets, hooks, etc are the examples of curved beams.

    - The different assumptions made during analysis of a curved beam are as follows:

    a) After bending, the plane of cross-section remains the same.

    b) The material obeys Hooke's law (Force is directly proportional to the distance by which the material has to be elongated or compressed) and is isotropic (identical in all directions).

    c) The material under compression and tension has same modulus of elasticity.
