The resisting bending moment is the product of the yield strength (of the beam material) and the section modulus of the beam. The RBM thus combines the material attributes as well as the geometric attributes of the beam and gives a useful metric to compare different beams irrespective of material or sectional geometry.
Plastic Section Modulus about the element local y-direction
The relation between bending moment and the second moment of area of the cross-section and the stress at a distance y from the neutral axis is stress=bending moment * y / moment of inertia of the beam cross-section
Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
Contrafluctre, or contraflecture, is the point in a bending beam in which no bending occurs. This is more readily and easily observed in an over hanging beam.
Yes, bending stress is directly proportional to the section modulus. A larger section modulus indicates that the cross-sectional shape of the member is better at resisting bending, leading to lower bending stress. Conversely, a smaller section modulus results in higher bending stress for the same applied bending moment.

the ability of beam or slab to resist failure in bending is called Flexural Strength of concrete.IIt is measured as modulus of rupture
Assumptions The beam is symmetrical about Y-Y The traverse plane sections remain plane and normal to the longitudinal fibres after bending (Beroulli's assumption) The fixed relationship between stress and strain (Young's Modulus)for the beam material is the same for tension and compression ( σ= E.e )
Plastic Section Modulus about the element local y-direction
section modulus is a measure of the strength of a beam. The more the section modulus the more is the strength.
The bending equation, also known as the Euler-Bernoulli beam equation, describes the behavior of a beam under bending loads. It relates the bending moment, beam material properties, beam geometry, and load distribution to the beam deflection. The equation is typically solved to determine the deflected shape of a loaded beam.
The relation between bending moment and the second moment of area of the cross-section and the stress at a distance y from the neutral axis is stress=bending moment * y / moment of inertia of the beam cross-section
Symmetrical bending occurs when a beam is loaded uniformly along its length, resulting in bending stresses that are equal on both sides of the beam's neutral axis. Unsymmetrical bending occurs when a beam is loaded unevenly, causing different magnitudes of bending stress on opposite sides of the beam's neutral axis.
Differential beam bending is when the beam is being bent at equally but at opposite sides. The beam can be bend in separate areas of a single beam or be two different parallel beams.
Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
