There will be an intermediate surface at which the stress is zero ("neutral" surface); the neutral surface cuts any cross-section in the neutral axis.doi:10.1007/978-1-349-15340-4_6A.M.I.Mech.E. G. H. Ryder M.A.CantabMacmillan Education UK...
Bending stress is highest at the top and bottom surfaces of the beam, known as thetensionandcompressionzones, respectively. These zones are located farthest from the neutral axis of the beam, which is an imaginary line that divides the beam into equal top and bottom portions. The magnitude of...

From classic bending theory thebending stress(σ) at any point in a beam is given by: σ=MI×y whereM= applied bending moment,y= distance of point considered from neutral axis, andI= second moment of area of cross-section of beam about the neutral axis. ...
At a plane in the beam cross-section, known as the "neutral plane" or "neutral axis," there would be no change in the length of the fibers and, thus, no bending stress, that is, the neutral axis is a plane of zero bending stress. 展开 ...
The bending stress formula is σ = M × c / I, where σ is the maximum bending stress at point c of the beam, M is the bending moment the beam experiences, c is the maximum distance we can get from the beam's neutral axis to the outermost face of the beam (either on top or ...
Shearing stress in the section of the beam with other shapes in section Iz is the moment of inertia of the whole section about z axis; V is shear force in the cross section Q is the first moment of the cross-sectional area below(above)the level at which the shear stress t is being ...
Then at the distance y from the neutral axis the stress in the steel reinforcing plates is (11.9)σs=Esɛ==MyIs+(EtEs)It because the strains in the steel and timber are the same at the same distance y from the neutral axis. This condition of equal strain is implied in the assumptio...
