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.
