Question

How the bending stress varies from top to bottom layer of the beam?

Answer 1

Answer:

When some external force acts on a beam, the shear force and bending moments are set up at all the sections of the beam  Due to shear force and bending moment, the beam undergoes deformation. The material of the beam offers resistance to deformation  Stresses introduced by bending moment are known as bending stresses  Bending stresses are indirect normal stresses
